Simple and compact

The METTLER TOLEDO RM40/RM50 refractometers are modern, compact instruments suitable for use in a vast diversity of application areas. They can be used, for example, in quality control as well as in research and development and meet the most demanding requirements.

These compact refractometers perfectly combine simple, easy-to-understand operation with an extremely high level of measuring accuracy and outstanding reliability. With their plug & play capability, they automatically detect external devices and sensors.

These refractometers can be operated as standalone instruments or run from a computer using the LabX PC software. Straightforward user guidance on the large color touchscreen enables intuitive operation. User-defin able shortcuts allow all functions to be activated directly from the home screen with a single click.

Touchscreen control of the instrument and the method function parameters are described in the Operating Instructions. The Installation Instructions explain all the necessary steps for setting up your instrument. You are then guided through the first refractive index measuring process with the aid of a practical example. If you have any additional questions, METTLER TOLEDO is always available to assist you.

7Introduction

2Description of the Refractometer

The RM40 / RM50 refractometers measure the refractive index nD of liquids. The two instruments differ in mea suring precision. Both instruments:

●

measure liquids whose refractive indices range respectively from 1.3200 to 1.7000 (RM40) and to

1.58000 (RM50).

●

require only minimal sample quantities for measurements (0.5 mL),

●

maintain the temperature of the sample constant with the aid of a built-in Peltier thermostat in a range from 5 to 100°C (RM40) and 5 to 75°C (RM40).

●

directly indicate the sugar content of samples in various sugar units (Brix, invert sugar, HFCS42 or HFCS55)

●

calculate the concentration of a solution by means of data from measured standard solutions, literature tables or formulas

●

are equipped with an integrated test function that enables regular testing of the accuracy of the measure ment,

●

enable checking of the product-related specification limits and generate rolling statistics.

The samples can be introduced manually with a syringe. For the optimal use of the RM refractometers, the fol lowing pumps and sample changers are available:

8 Description of the Refractometer

●

A maintenance-free LED is used as a light source for the measurements.

●

The measuring prism is made of sapphire. It is therefore extremely corrosion resistance and very robust. It also has a high thermal conductivity.

●

For temperature measurement, NTC thermistors with extreme long-term stability are used. This means that there is no need to regularly readjust the measuring cell.

3.1Definition of the Refractive Index

The refractive index of a substance is the ratio of the speed of a light beam in a vacuum to its speed in the sub stance (dimensionless).

If a light beam crosses at a certain angle from an optically less dense to an optically denser medium (e.g. from air to water), it is deflected; when the beam crosses from one medium to another perpendicularly no directional change takes place. According to Snell's law, the ratio of the refractive index of the two media is proportional to the ratio of the incident and refrac tive angle of the light beam:

If a light beam passes from an optically denser to a less dense medium, it is also deflected. If the angle of incidence α is increased, then it reaches a critical value, at which the light beam no longer enters the less dense medium (refractive angle

= 90°). When this "critical angle" is exceeded, total internal reflection occurs. The refractive index is calculated from this critical angle α :

As refraction depends on the wavelength of the incident light, the refractive index n is measured as standard with the D line of sodium (wavelength 589.3 nm) and designated nD.

The refractive index not only depends on the wavelength of the light but also on the temperature of the mea sured sample. For this reason the temperature must always be stated along with the result, e.g. n The standard temperature is 20 °C.

3.2Method of Measurement

= 90o —> sinβ =1

1: Critical angle 2: Total internal reflection

The light emitted from the light source passes through the prism and hits the sample. In the process it is partly refracted (angle of incidence < critical angle) and partly reflected (angle of incidence > critical angle).

The reflected light is measured by means of an optical sensor (CCD). The boundary between the dark and light area corre sponds to the critical angle required for calculation of the refractive index.

1: Light source 2: Prism 3: Sample 4: Optical sensor (CCD)

3.3Design of Measuring Cell

The light source is a light-emitting diode (LED), whose beam passes through a polarization filter, an interfer ence filter (589.3 nm) and various lenses before it reaches the sample via the sapphire prism. The reflected light (angle of incidence > critical angle) is deflected via a lens to the optical sensor that determines the critical angle. The temperature in the prism/sample boundary is measured with a built-in sensor.

A distinction should be made between the following two cases in the installation of instruments:

There is still no setup entry available in the unit (delivery state). A new entry has been generated and the parameters automatically generated.

A setup entry was previously manually created in the instrument: The PnP parameters are automatically entered, the remaining parameters, previously edited by the user, remain unchanged.

18 Setup

When a PnP instrument is unplugged, the status changes to "not installed".

Below is described how you can administer the various devices in setup. This includes the creation of devices or changing the parameters in the setup.

Create automation units

So that methods for the application of automation units can be created and configured without the automation unit being connected, these units must be created in the setup via the button New.

Delete automation unit

It is not possible to delete the entry of a connected device.

If you want to delete an entry for a unit that is not connected from the list, a message with the termination option appears indicating that after deletion the methods that use the external instruments will no longer be exe cutable.

5.2.3External Instruments

●

The Lovibond colorimeters can be connected to the USB interfaces. For this purpose the USB – RS232 adapter is required (contained in the connection kit).

●

For each device type only one entry is possible.

Install devices

A distinction should be made between the following two cases in the installation of instruments:

There is still no setup entry available in the unit (delivery state). A new entry has been generated and the parameters automatically generated.

A setup entry was previously manually created in the instrument: The PnP parameters are automatically entered, the remaining parameters, previously edited by the user, remain unchanged.

When a PnP instrument is unplugged, the status changes to "not installed".

●

Via the button External instruments in the Hardware dialog, you can obtain the list of instruments. By touching a list entry, you obtain more detailed information about the corresponding instrument.

Create device

So that methods can be created and configured with external instruments, without having to connect the instru ment, the setup entries of the external instruments can be manually created via the button New.

●

The pH and conductivity meters can be assigned names individually using the "Instrument" parameter.

Delete devices

It is not possible to delete the entry of a connected device.

SevenEasy™ / SevenCompact™ pH/ion and conductivity meters

1 Select the following for the SevenEasy™ and SevenCompact™ measuring instruments (also refer to the

operating instructions for the measuring instrument concerned):

Manual end point measured value acquisition, set the unit [pH]" ([mV] not supported).

2 For the SevenCompact pH and conductivity meters, the following must also be selected (also refer to the rel

evant operating instructions):

an interval time of 1s (in menu>Interval measurements), interface=printer (in menu>Data transmission), "Send data to interface" (in "Type of data transmission").

19Setup

3 For temperature compensation, set the unit [°C] at the measuring instruments. Two types of temperature

compensation exist:

- ATC (automatic temperature compensation) with a temperature sensor connected.

- MTC (manual temperature compensation) with no temperature sensor connected. Note: The pH or conductivity meters switch automatically, depending on the arrangement. If the temperature unit at the pH meter or conductivity meter is set to [°C], the results "TpH" and "TCond" will be converted to the temperature unit set in the instrument, i.e. either [°C] or [°F] . By contrast, if [°F] is set at the pH or conductivity meter, no result will be calculated. "--" will be output in the results field.

The conductivity units are [mS/cm]/ [μS/cm] (depending on the range) or [mS/m][μS/m] (depending on the range). However, the results are expressed in [μS/cm]. If you wish to have the result displayed in [mS/cm] or [mS/m][μS/m], it will be necessary to recalculate the result using the "Calculation" method function.

Colorimeter

- Lovibond

The Lovibond colorimeter can be used for extinction or transmission measurements. The wavelengths are out put in 5nm (in the range 420 – 710nm).

A color measurement may take longer than 25s.

- Minolta colorimeters CM-5 / CR-5

The Minolta colorimeters can be used for transmission measurements (liquids). Transmission data are supplied in 10nm increments within the spectral range 360 – 740nm. A color measurement takes approximately 1s. The measurements involve high-energy light flashes. For this reason, color scales are not offered for reflection measurements in the crude oil industry.

●

The CR-5 colorimeter does not supply any spectral data.

●

Calibration is possible directly at the colorimeter only. The USB link must be disconnected.

6Methods and Products

Before you can perform a measurement you need a method. A method is an analysis program and consists of a sequence of method functions (some with method subfunctions), which are processed by the instrument in sequence.

Products are always linked to a method, and multiple products can be linked to the same method. It is therefore possible to work with only a few methods.

Using the Print button, you can generate a PDF file containing the methods or product parameters and product calculations.

The Print button is active only when a USB stick is connected.

How to create methods and products, how to access them and apply them is described below.

6.1Methods

A method basically consists of the configuration, sample feed, the actual measurement, cleaning, result calcu lation and the creation of a report. These steps are defined as functions. The individual functions in turn consist of parameters, whose values or names can be changed.

Method types

The instrument distinguishes between the following method types with different objectives:

●

MS (Measurement), for the performance of a measurement

●

ADJ (Adjustment), for an adjustment of the measuring cell(s)

●

TE (Test), for testing the measuring cell(s)

●

CL (Cleaning), for cleaning the measuring cell(s)

6.1.1Establishing Methods

When creating methods (max. number of methods: 30) you can make use of method templates with prede fined method types and hence structures. The corresponding parameters thereby contain suitable default val ues.

Select: Home > Methods / Products > Methods

1 Choose New to create a new method on the basis of a template.

2 Select the desired method type from the available templates. Now you can adjust this method to your own

specifications by adding or deleting method functions, or by adjusting the settings.

After a template has been chosen, the Configuration dialog opens. Here, according to the defined setup, you can select the cell mode, the cell, automation unit and the external devices (pH, conductivity and colorimeter) with which you wish to carry out the method.

Parameters Description Displayed if

Cell mode Defines the cell(s) Automation Defines the automation unit used by the method. The choice

available depends on the automation units defined in Home >

Wait time Col The colorimetric measurement begins after this time has elapsed.

In the case of multiple measurements, only the first measurement is started after this wait time has elapsed. All other measure ments begin with no wait time.

End point Fixed duration:

External instrument = Colorimeter ("Configu ration" method tem plate: "Color" activated)

The measurement is stopped after a certain time. This function is used to shorten the measurement time if high precision is not required. The measurement is stopped on achievement of the maximum measurement reliability at the latest.

Refill ratio Measurement for further movement of the sample between two

measurements. The refill ratio is calculated using the duration of the sample addition. For example: The addition duration is 10s and the refill ratio is 50%, i.e. pumping continues for 5seconds.

Max. SD Maximum permitted absolute standard deviation of the measure

ments for density, refractive index or color. When the deviation is exceeded the measurement is interrupted with the status "Error".

The maximum standard deviation must be entered in the function of the measuring cell type. The default value in the method is provided for an R40 cell. This should be adjusted for an R50 cell, e.g. 0.00002.

For the calculation of the standard deviation SD of the color results, the first color result in the formula of the "Calculation" method function with the smallest Rx index is used. If no color result is included in the calculation, "–" will be displayed for the standard deviation, i.e. SD is within Max. SD.

Single values (d1 to d10) are available as raw results and can be used in a calculation (i.e. for a 3-fold mea surement all 3 single values can be reported).

Repeat if failed If this is activated, the measurement is repeated if a bubble check

Parameters Description Displayed if

Max. test dura tion

Maximum duration of the cell test in [s]. If the measured value has not stabilized by this time, the cell test will be interrupted and counts as having been failed.

test is failed. The task list is interrupted. If the parameter has not been activated, the measurement proceeds as normal, even if the cell test has been failed.

6.1.7.11Temperature Compensation

Temperature compensation allows you to measure a sample at a temperature and then to output the measured value at another temperature. This temperature compensation is used in the following cases:

●

The measured value must for example be stated at 15°C, however the sample is too viscous at this tem perature. Therefore these samples must be measured at correspondingly higher temperatures so that they can be pumped to the measuring cell and remain fluid there.

●

For accelerated measurements. If the sample is delivered at 35°C for example and the measured value is required at 15°C, the sample can be measured at 35°C and the measured value can be compensated to 15°C.

●

If the required reference temperature is outside the range of the measuring instrument (e.g. 120°C), the sample can be measured at 75°C and the result compensated to 120°C.

To use the temperature compensation, the temperature dependence of the sample must be known.

If you have connected a density - module, you can also use the API table (ASTM-D 1250). The following tables are used (for crude oils, refined products, lubricants):

●

53A, 53B and 53D for 15°C

●

5A, 5B and 5D for 60°F

●

59A, 59B and 59D, for 20°C

The aforementioned ASTM or API tables take as input values the readings taken from a hydrometer, which do not however make allowance for the coefficient of expansion of the glass hydrometer. Therefore the measured density cannot be directly used as the input value for these tables.

The measured values are converted to the desired temperature. The output value (TC) of this method function can be used in the method function "Calculation".

6.2.1Create Products

Select: Home > Methods / products > Products

You create a new product if you either select and configure defined products from the list and save them under a new ID or generate a completely new product. The following description shows how you can generate a new product:

Open the method selection window via the button New in the Products dialog. Here all the methods of the type Measurement are listed that can be assigned to a product.

1 Touch the corresponding method in the list that should be assigned to the product.

The Product dialog is opened. The parameter "Linked method" shows the ID of the selected methods. Note: You can retrospectively assign another method to the product (same configuration).

2 You can edit and configure product parameters, assign the product an ID and a title.

You can start the product immediately or return to the product editor.

6.2.2Linking Methods with Products

A distinction is made between two cases:

A product is created and linked with a method. On linking of a product to a method (before saving the first time) the values are taken over from the linked

method.

A product has been previously created, the linked method is changed (relinking). In this case only the methods for the relinking are suggested that agree with the currently linked method in

the configuration. After initial saving, the product parameters are not overwritten by the parameters of the method. For the measurement the product parameters are: such as e.g. Multiple measurements, Calculations (Coeffi cients and result limits) are used and not the parameters of the corresponding method. The entries in the method however remain unchanged.

●

When you start a product measurement, the parameters defined in the method are "overwritten" by the prod uct parameters.

●

A maximum of 100 products can be defined.

●

If no measurement methods have been defined on the device, no product can be created.

●

Product ID’s can be used for barcode recognition.

●

Several products can be linked to the same method.

●

A product is always assigned to exactly one method.

●

When a method is deleted, all linked products are also deleted.

●

If a product is saved under a new ID, the values are retained in the product and are not overwritten by stan dard values from the method.

10.5Start with Barcode Reader

The following two barcode reader types can be connected to the device:

●

Handheld readers

●

Built-in reader, this can be integrated in the sample changer (SC30 or InMotion).

69Analysis Sequence

Under Home > Setup > Hardware > Peripherals > Barcode readers you can configure the barcode readers. Here the information contained in the barcode and the format can be specified. If the barcode contains the sample, method or product ID you can also activate the parameter "Immediate start". When you are in the Start analysis dialog and scan in the barcode of a sample with a new sample ID, the bar code is transferred to the parameter "Sample ID". The task starts immediately. The most recently completed method starts with the new sample ID.

●

The specified data from standards can be scanned in for adjustments and tests. To do this, start an adjusting and test method. In the Start analysis dialog touch the Default, whereupon the Default Data dialog opens. This displays the standard data that you scanned in with the barcode.

●

Test methods can be started via barcode.

10.5.1Start with Handheld Reader

If you are in the Homescreen, the online screen or in the task list, you can start an analysis by scanning in a barcode. Depending on the information in the Barcode reader parameters dialog (Home > Setup >

Hardware > Peripherals > Barcode readers), a distinction is made between the following sce

narios:

Parameter "Barcode information" = "Sample ID": After the barcode has been scanned, the Start analysis dialog is displayed. Here you can select the method/ the product, with which the analysis is to be performed. By pressing Start the analysis is started.

Parameter "Barcode information" = "Sample ID/Method ID" or "Sample ID/Product ID": After the barcode has been scanned, the Start analysis dialog is displayed. By pressing Start the analysis is started.

Parameter "Barcode information" = "Method ID" or "Product ID": After the barcode has been scanned, the Start analysis dialog is displayed. Here you can enter the sample ID.

If "Immediate start" is activated in the setup of the barcode reader, then the analysis is immediately started, i.e. without the Start analysis dialog being displayed. The sample ID defined in the method is adopted.

10.5.2Start with Built-in Barcode Reader

If a built-In barcode reader is connected, the button BC Start appears in the Homescreen (this button is only activated, if no task is lined up). By pressing this button the Start analysis dialog is displayed. Depending on the information in the Barcode reader parameters dialog (Home > Setup > Hardware >

Peripherals > Barcode readers), a distinction is made between the following scenarios:

Parameter "Barcode information" = "Sample ID": In the Start analysis dialog you can select the method/ product, with which the analysis is to be performed (all analyses are performed with the same method/ product). After Start is pressed, the barcode of the first sample vial is scanned in and the first analysis started. The vials are sequentially processed until an empty item appears on the sample changer (SC30 or InMotion).

Parameter "Barcode information" = "Sample ID/Method ID" or "Sample ID/Product ID": After Start is pressed, the barcode of the first sample vial is scanned in and the first analysis started. The vials are sequentially processed according to the method/product information on the barcode. If there is an empty position on the sample changer (SC30 or InMotion), the analysis sequence is terminated.

Parameter "Barcode information" = "Method ID" or "Product ID": After Start is pressed, the barcode of the first sample vial is scanned in and the first analysis started. The vials are sequentially processed according to the method/product information on the barcode. The sample ID is taken over from the method or from the Start analysis dialog. If there is an empty position on the sam ple changer (SC30 or InMotion), the analysis sequence is terminated. By touching Stop or Reset you can cancel the analysis sequence at any stage.

10.5.3Start with ErgoSens

The ErgoSens is a movement sensor. A hand movement in front of the sensor immediately starts the method, productor series most recently used by you.

70 Analysis Sequence

If you have activated the parameter "Confirm end of the analysis", at the end of the analysis a confirmation via the ErgoSens takes place; instead of confirmation by OK.

An analysis start by barcode with the ErgoSens can be initiated with the button Barcode start (for SC30) (if the last start was initiated with this button).

10.6Continuous run

At the start of a measuring method or product by the editor, homescreen or a shortcut, you can select "Continu ous run". At the end of an analysis, the same analysis will start again automatically after the defined wait time (interval). If a sample changer (SC30 or InMotion) is used, the sample vials are processed successively until an empty space is found on the sample changer. The sample ID receives the suffix "__01" and is incremented.

An analysis with the "Continuous run" parameter activated is terminated in the following ways:

- via Stop button,

- in the event of a fatal error,

- if no more sample vials are available (SC30 or InMotion).

10.7Analysis Termination

Ongoing analyses can be canceled in the online screen via the button Stop or Reset (detailed information on the online screen can be found in"Tasks and online screen (page73)"). The current analysis is stopped and the processing of the next task is interrupted. To continue the waiting tasks, open the task list (with the Tasks button) and press Continue.

10.8Errors in the Analysis Sequences

Analyses can exhibit faults. Three types of faults can be identified during an analysis sequence:

●

Error (e.g.: max. fill duration exceeded)

●

Error with termination (e.g.: sample needle on the SC30 block)

●

Critical error (e.g.: fan stopped)

10.8.1Malfunction Types: Error

Malfunctions of the type Error are for example:

●
