Section 1 - Introduction
1.1Instrument Description
The 67 Series offer a range of unique features and functions to help in the management of methods and data at both individual and multi-user levels.
These units have a specially designed user interface based on a high quality, colour TFT LCD with touch screen technology and QWheel™ support to provide ease-of-use for all operations from set-up to measurement and data handling.
Five main measuring modes are available: Photometrics, Spectrum, Kinetics, Quantitation and
Multi-Wavelength.
The 67 Series have dual memory options that enable you to store settings and data to either internal memory or on a removable SD/Multi-Media memory card. By saving to the removable SD card all settings, methods and results specific to the user can be retained by the individual, offering additional security and allowing easy transfer of data to a PC for storage, manipulation or off-line review. The SD card can also be used in any similar model, giving complete flexibility to use any available instrument. A simple back-up procedure enables easy transfer of all information from the internal memory to the removable media while quickly enabling a group of instruments to be cloned with identical settings.
It is possible for any user to perform simple measurements (Free Operation) at any time, however, logging-in with your own PIN code will allow you to create methods, change settings or store results. Each method can be designated as Public (for open user access), Read-Only (available for all users as read-only information) or Personal (only accessed through your PIN code).
A number of sampling accessories are available as complete, easily interchangeable modules. These include a Sipper Pump, Sipper/Peltier, Automatic Cell Changer, plus a comprehensive range of passive cuvette and test tube holders, which can be fitted in the single cell holder accessory.
The PC Software supplied enables the transfer of data from the instrument or SD card to the PC with rapid copy and paste into spreadsheets or other computer programmes.

1.3Good Practice Guidelines
1.For optimum performance all spectrophotometers should be sited in a clean, dry, dust free atmosphere. When in use ambient temperature and light levels should remain as constant as possible.
2.Adherence to Standard Operating Procedures (SOP) and Good Laboratory Practice (GLP) should be monitored with regular calibration checks and a suitable Quality Control (QC) programme.
3.The sample chamber lid must be fully closed during measurement and before any readings are recorded or printed.
4.The correct selection of sample containers is imperative for accurate and reproducible results:
a)Check that the material of the sample container is compatible with the wavelengths to be used for measurement. In general glass can only be used down to 360nm or 320nm depending on quality. Standard plastic cuvettes can be used down to 320nm. Special UV versions can be used down to 260nm. Below this level quartz cuvettes must be used.
b)Plastic disposable cuvettes should be used ONCE only.
c)Glass cuvettes should be thoroughly cleaned after use. Discard when scratches become evident in optical surfaces.
d)Care should be taken when selecting semi-micro or micro cuvettes. The cuvette window on the inner chamber (the area filled with sample) must be wider than the aperture in the sample holder or light will reach the detector without passing through the sample. In this case, semi-micro or micro cuvettes with self-screening black surrounds must be used or alternative holders for these cuvettes fitted.
e)Glass test tubes and other sample tubes should be used with care. Where possible, matched tubes should be used and any index mark set to the correct position before measurements are made.
f)Ensure any sample containers used are compatible with the constituents of both the samples and standards they are to hold. Plastic cuvettes are not compatible with organic solvents.
11
g)All sample containers must be handled with care; by the top and non-optical surfaces only. Any finger marks evident must be removed using a suitable cleaning process.
h)Flow-through cuvettes must be selected with care and consideration for the sample type, sample volume, pumping system, rinse, sample and waste handling to be used.
5.Samples and standards should not be stored in open cuvettes or sample containers as evaporation will change the value and lead to staining of the walls which may be irreversible. If stored in stoppered and sealed cuvettes, they should be filled with little or no air space and the values regularly checked against a reference standard or quality control material.
6.Cold samples should be allowed to equilibrate to ambient temperature before measurement (unless a suitable temperature controlled sample holder is in use). Temperature change during measurement may cause air bubbles to form on the walls of the sample holder. This is a common cause of drift during measurement.
7.In the preparation of samples and standards high grade borosilicate glass and AR grade chemicals and reagents must be used. Good quality deionised water or other suitable solvent must be used for dissolving or diluting samples, chemicals and reagents.
8.All measurements require calibration to a blank, for maximum accuracy this should be prepared with care using the same deionised water or solvent used for dissolving or diluting the sample. Where reagents are added to the sample to produce a colour proportional to its concentration a ‘sample based’ blank should be used. In this case the blank should consist of the sample plus any reagents or chemicals to be used, except those that produce the colour to be measured.
9.Deviations from the Beer-Lambert Law may occur at high and low concentrations giving non-linear response during sample concentration measurements. For all new methods a linear range should be defined by the preparation of a calibration curve. The quantitation mode may be used to construct such a curve against which sample results are automatically measured.
10.Cuvettes and sample holders must be filled to a minimum level which covers the light path.

Section 2 - Getting Started
2.1Unpacking Instructions
•Refer to label 1 on carton exterior and ensure instrument type and options/ accessories supplied are correct. Refer to Distributor in the event of any discrepancy.
•Check each item as it is removed from the packaging to ensure it is correct and
undamaged. Refer to Distributor if any item is missing or damaged.
•Remove Documentation carton 2. Note that this contains the Instruction Manual and other important documents, which MUST be retained for future reference. Other small items (CD ROM, SD Card etc) will also be found inside this carton.
•Please take some time to familiarise yourself with the contents of the Instruction Manual before using the instrument for the first time.
•Remove the cardboard packing piece 3 and place to one side.
•Remove the two foam packing pieces 4 and place these to one side.
•Grasp the instrument 5 (which will be sealed in a polythene bag) firmly at each end, and lift out of the carton to place on an adjacent flat, firm and clean surface.
The instrument weighs approximately 10 Kgs.
PLEASE TAKE CARE WHEN LIFTING.
• Remove the Accessory carton 6. Note that this contains the Power and USB cables together with any sample cells or other items that may have been ordered. Refer to the Instruction Manual to ensure accessories are installed correctly before using the instrument for the first time.

1
It is recommended that the Instrument packaging be retained for possible future long-term storage or transportation. Please note that the Manufacturer or Distributor cannot be held responsible for any damage incurred as a result of transportation of an inadequately packed instrument.
13
If you wish to dispose of the instrument packaging, please do so in an environmentally responsible manner. Please refer to the following guidelines: -
Cardboard packing items are made from paper sourced from recycled fibres or managed forests and can be 100% recycled where appropriate facilities exist. Ensure cartons are crushed or flattened before disposal.
Foam packing pieces are manufactured with a reprocessed polyethylene content and can be easily recycled with other low-density polyethylene (LDPE) materials. Polyethylene foam is manufactured by a CFC and HCFC free process and contains less than 100ppm heavy metal content. The European Union Packaging Directive confirms that recovery by means of waste- to-energy is a sensible waste management alternative. The Polyethylene foam burns cleanly and contributes a high calorific value.

Section 3 - Systems of Operation
3.1Multi-User and Free Operation
The 67 Series spectrophotometers focus on secure, multi-user operation. But to ensure that anyone can acquire quality results in an emergency or when otherwise required (stat or free operation), they may also be used without the operator having to log in. Such free operation is restricted to making measurements with no access to methods while results will only be displayed or printed.
Secure, multi-user operation requires each designated user to enter a PIN code to access methods and results. When creating methods a user can opt to share them with other users, as Public (can be modified) or Read-Only (can be used but not modified), or to keep them Personal. Up to 10 users and a Supervisor with administrative rights can be set up on each instrument but by using the removable media (see below) an almost infinite number of users can be securely accommodated.
3.2Memory Structure
The 67 Series spectrophotometers have a dual memory structure based on removable media and fixed internal memory. The removable media is based on SD memory cards with a wide range of capacities available.
The following table gives details of the removable media available (subject to change by manufacturers range consolidation):
Card Capacity |
SD Card Part Number |
2 GB |
019 133 |
|
|
3.2.1Memory Selection
When the power is turned on the internal memory is selected as the default memory location, even if a removable memory card is fitted in the instrument. If the user inserts a removable media memory card during use a message will be displayed giving the user the option to switch the default memory
location to the removable media memory card so that any methods and results that are saved are sent to this card. Should the card be removed during use a warning message will be displayed and the internal memory will then be set as the default location.
23
3.2.2Memory Hierarchy
The top level of the memory hierarchy is the user, defined by a user name and recognised by their unique PIN code. In general it is considered that this will be an individual but in practice this can be made more flexible by considering the user as a group sharing the same PIN code. For instance different departments or shifts could be identified by their own PIN codes.

Methods
Created by User
Results appended to user accessible methods
Different types of tests could also be separated by PIN codes with only users trained in carrying out specific tests given the relevant PIN codes to access the tests for which they have been trained. In education a PIN code for each semester or part of the curriculum would restrict students or year groups access to only the current work, protecting that to be used in the future. The implementation and benefits of this function are only limited by the imagination.
Below the user level are the Methods created by that user or for that group, and those with Public or Read-Only status that all users can access, below each method are the results stored by the user for that method.
3.3Creating Methods
The ability to create and re-call methods is only available to logged in users.
To log in touch the Log In… key on the bottom right-hand side of the Main Menu screen that is displayed after completion of the start-up tests.
A table of users is then displayed, touching your name (department, user group or other identifier) then brings up a numeric entry screen for inputting the four digits of the relevant PIN code.
For first time use the only user in the table will be the Supervisor with a default PIN Code of 1234 (once logged in this can subsequently be changed to a number combination of the Supervisor’s choice).
By pressing the Settings key on the display surround and selecting the Administrative Functions option the Supervisor can create new users. On creation a new user has a default PIN Code of 0000 that, like the Supervisor’s, can be changed by selecting User Preferences, then Adjust PIN Code.
NOTE: Once the Supervisor’s PIN CODE is changed it must be kept safe as there is no other way of accessing this function – however the Supervisor does have the right to re-set other users’ PIN Codes back to the default.
For further information on these functions see the Section on Instrument Settings and
Administrative Functions.
24
When successfully logged in the user is returned to the main menu screen from which the required mode of measurement can be selected.
The Browse screen is then displayed from which an existing method can be re-called using the alphanumeric search keys along the bottom menu bar. If insufficient methods have been created to fill the first page all available methods will be shown.

Saving Methods
Having entered all your required settings on the tabbed pages the method can be saved by simply pressing the Save key on the display surround. If you do not save at this point but continue to make measurements using the method, it will automatically be saved when you save the first result.
If you continue without saving a result you will be prompted to save the method as you exit the operating mode or return to the settings options. Alternatively, when the Auto Log option is set to On or Timed and the destination option is Memory all results will be saved automatically.
Sharing Methods
Methods can be shared with other users by setting the security level at either Read-Only where other users can use but not modify the method or, Public where they can use and modify the method. Other users must then ensure that under Method View Settings (Settings/User Preferences/Method View Settings) they have enabled Public and/or Read-Only methods or turned All Methods on.
Recalling Methods
Following selection of the operating mode from the main menu the method browse screen is displayed. This will show all methods that the current user has access to, based on their selections in the Method View Settings (refer to Sharing Methods). If the first page is full, cursor arrows will be displayed to enable navigation to and from additional pages.
Alternatively, selection may be made using the alphanumeric menu bar at the bottom of the screen.
Repeated pressing of each character set will display the full alphanumeric range and the screen will show all methods starting with the highlighted character.
Touch the required method when it is displayed on the screen to highlight it, touch the Open File icon to display the main measurement screen for that method.
Editing Methods
Use the Recalling Methods procedure to recall the required method. With the measurement screen displayed touch the Settings option. Adjust the settings as required and touch the Enter icon
on completion. The modified method can then be saved by pressing the Save key on the display surround. If you do not save at this point but continue to make measurements using the method, it will automatically be saved when you save the first result. If you continue without saving a result you will be prompted to save the method as you exit the operating mode or return to the settings options.
Note: If the Method name was not changed during editing it will be saved with the same name but with a new date and time to ensure traceability. If the old method is no longer required it should be deleted as detailed in Deleting Methods.
25
Deleting Methods
To delete methods highlight the required method in the Browse screen as described in Recalling Methods and then touch the Erase icon.
A warning message will be displayed to ensure this action is required. On confirmation the selected file will be deleted.
If the current user does not have the required privileges to delete the selected method then an information message will be displayed advising that the method cannot be deleted.
Privileges required for deleting designated methods:
Public Methods – only the Supervisor and Originator can delete these.
Read-Only Methods – only the Supervisor and Originator can delete these.
Personal Methods – Only the Originator can delete these methods. (The Supervisor can delete these by resetting the Originator’s PIN code and then logging in as the Originator).
Saving Results
After completion of a measurement the result can be saved by simply pressing the Save key on the display surround. The result is saved under the method that created it, with the entered Batch ID and an incremental number along with the time and date of the measurement. Results can also be saved as part of the Auto Log function by selecting Memory under the Auto Log option, which will vary depending on the type of sampling accessory fitted.
Printing Results
After completion of a measurement the result can be printed, by simply pressing the Print key on the display surround. The result will be printed to either the internal or external printer, as selected by the user in the Printer Settings option.
The first result of any new batch is preceded by a print header, which gives details of the method settings and Batch ID. Results can also be printed as part of the Auto Log function, which will vary depending on the type of sampling accessory fitted.
Recalling Results
Stored results are always directly linked to the method that created them. To access results first recall the method as described in Recalling Methods. With the method highlighted touch the Search Results icon. This will open a screen detailing all results available to the current user. Touch the required result or batch (depending on the mode) and then the Open Specific Result icon. This will display the results on the screen. The Tools option can then be used to work on these results (depending on mode). It is also possible to print the result by simply pressing the Print key on the display surround. Options to print to the Internal or External printer or to the CSV file will be displayed. Printing to the CSV (Comma Separated Values) file will save the data in CSV format on the external data card. (If a card is not fitted the instrument will display a prompt). This is in text format and can be viewed and printed in Excel®.
In Kinetics mode an additional option is available (Analogue Mode). This allows results to be output via the rear panel analogue sockets to a chart recorder or similar device.
Sharing Results
Results attached to Personal Methods cannot be accessed by any other user.
Results attached to Read-Only and Public Methods can be accessed by all users, based on their current
Method View Settings.
