1.1 Instrument description

1 Introduction

1.1 Instrument description

The 793 IC Sample Prep Module consists of a reactor block (SP Module A) with its corresponding control unit; this contains an addi-

tional 2-channel peristaltic pump.

Inline sample pretreatment like neutralization or cation exchange for ion chromatographic analyses can be carried out with the cation exchanger built into the SP Module A. The SP Module A contains three cation ex- change units which are in turn used for cation exchange, regenerated with acid and rinsed with water. In order to perform each analysis under comparable conditions a freshly regenerated cation exchange unit is normally used. Switching is either carried out automatically by the IC system or manually. Due to possible interference of sulfate with the IC determination, perchloric acid is normally used for cation exchanger regeneration of the SP Module A instead of sulphuric acid.

At the control unit the SP Module A can either be switched to the next position manually or by remote control via the remote interface. The built-in peristaltic pump, which delivers the solutions required for operating the SP Module A, can also be switched on by remote control or manually.

The 793 IC Sample Prep Module is particularly suitable for retrofitting a modular anion IC system for inline sample pretreatment in a simple manner. Two typical applications are described in detail in these instructions for use: Neutralization (e.g. exchange of Na Cation Separation (e.g. exchange of heavy metals by H the 793 IC Sample Prep Module can also be combined with all other HPLC components currently on the market.

Although in principle the techniques of cation exchange by the 793 IC Sample Prep Module and suppression by the 753 Suppressor Module are comparable, the 793 IC Sample Prep Module is not suitable for chemical suppression after ion chromatographic separation of anions.

2 Installation

2.3 Connection to a Modular IC System for Neutralization

An important application for the 793 IC Sample Prep Module is neutralization of an alkaline sample for anion determination by IC with chemical suppression. Strong bases (e.g. 30 % NaOH) should not be led unlimited to the SP Module A. To provide a sufficient capacity for exchanging

by H+ Ions, only a small fraction (e.g. 20 µL) is directed to the SP

Na Module A using a sample loop. The analyte anions are preconcentrated subsequently on a preconcentration column and finally eluted to the separation column in counter flow by the eluent.

Therefore, such an IC system corresponds to the Modular IC System 6 (MIC 6: Anion system with chemical suppression, preconcentration and matrix elimination) enhanced by the 793 IC Sample Prep Module.

If the sample doesn’t require matrix elimination and preconcentration, it can be treated directly by the SP Module A. This could be an option for samples containing only low amounts of the cations which have to be eliminated. For this purpose, a system as described in section 2.4 should by used.

The following pages describe the electronic connections of this system in combination with the 766 IC Sample Processor on the base of full control by «IC Net 2.1».

2.3.1 Electrical connection

The 793 IC Sample Prep Module is connected to an IC system consisting of 732 IC Detector, 733 IC Separation Center (two injectors), 709 IC Pump, 752 IC Pump Unit, 753 IC Suppressor Module and 762 IC Interface as shown in Fig. 5.

16 16

connected to the event line “fill” of the 733 valve B instead, using the

6.2128.180 cable. Thus the suppressor is switched when the fill position is accessed by valve B.

2.3.2 Connection of the SP Module A

The following description implies the usage of the 2.733.0120 IC Separation Center (two injectors).

The 1.793.0110 SP Module A must first be inserted in the 733 IC Separation Center and connected to the 793 IC Sample Prep Module. Additionally, the suppressor block of the 753 Suppressor Module is inserted and connected, which is described in detail in the corresponding

x Before using the SP Module A for sample pretreatment, its

cation exchange material should be conditioned. Inject 30% sodium hydroxide 15 times (five injections per unit) using the sample program of the system “Neutralization” as described in the following section. The run time can be 20 min. each while the separation column doesn’t have to be installed.

Pump tubings are consumable material with a lifetime which depends on the contact pressure. This is why the tubing cartridges should be raised completely by loosening snap-action lever

on the right-hand

2 Installation

2.3.3 Settings in the «IC Net 2.1» program

During configuration of the 793 IC Sample Prep Module and 753 Suppressor Module the IC Net assistant “New system wizard” requires the definition of “Event lines” for the SP Module A and suppressor, respectively. Although these lines are not installed you must enter any unused “Event line” to enable the program to proceed. Actually, the SP Module A is controlled by the 766 sample processor, while the suppressor is controlled by the event line from 733 valve B (see Fig. 5).

A main program for the system “neutralization.smt“ is defined together with two programs for extra systems for the 766 IC Sample Processor. “start-neutralization.smt“ starts the 752 Pump. Furthermore, the SP Module A is rinsed at all three positions. “end-neutralization.smt“ turns off the 752 Pump..

The peristaltic pumps of the 753 IC Suppressor Module and 793 IC Sample Prep Module are started when the IC system is activated (measuring baseline). For this, the option ’Start pump with startup

hardware

2.4 Connection to a Modular IC System for Cation Elimination

A second application for the 793 IC Sample Prep Module is cation elimination before chromatographic separation of the sample on the column (e.g. precolumn elimination of heavy metals). In this section a system for determination of anions with chemical suppression is described. It includes the application of the sample to the SP Module A followed by filling the sample loop with this pretreated sample. Therefore, such an IC system corresponds to the Modular IC System 2 (MIC 2: Anion system with chemical suppression) enhanced by the 793 IC Sample Prep Module.

If you are not sure about the required capacity for complete cation elimination and/or if the sample requires matrix elimination and preconcentration in combination with cation elimination by the SP Module A, a system as described in section 2.3 should by used.

The following pages describe the electronic connections of this system in combination with the 766 IC Sample Processor on the base of full control by «IC Net 2.1».

2.4.1 Electrical connection

The 793 IC Sample Prep Module is connected to an IC system consisting of 732 IC Detector, 733 IC Separation Center (one injector + MSM), 709 IC Pump, 752 IC Pump Unit and 762 IC Interface as shown in Fig. 5.

3 Operation

3.1 Handling the SP Module A

General

The SP Module A of the 793 Sample Prep Module consists of a total of three cation exchange units which are in turn used for cation exchange, regenerated and rinsed with water. In order to record each new chromatogram under comparable conditions a freshly regenerated cation exchange unit is normally used. Switching is either carried out automatically together with valve switching or manually.

Correct connections

The three inlets and outlets numbered 1...3 on the SP Module A each have 2 permanently mounted PTFE capillaries, which must be connected as described in sections 2.3.2 or 2.4.2 respectively (see Fig. 6).

Flow direction

The cation exchange units must never be regenerated in the same flow direction used for the sample. You should thus always install the inlet and outlet capillaries as described in sections 2.3.2 or 2.4.2 respectively according to the scheme shown in Fig. 6.

Never switch when dry

The SP Module A must never a danger of blocking.

No recycling

The recycling process (returning the eluent to the storage vessel) must not be carried out when the SP Module A is in operation.

4 Malfunctions - Maintenance

4.2 Maintenance and servicing

4.2.1 Care

The 793 IC Sample Prep Module requires proper care and attention. Excessive contamination of the instrument could possibly lead to malfunctions and a shorter service life of the inherently rugged mechanical and electronic parts.

Spilled chemicals and solvents should be wiped up immediately. It is especially important to protect the plug connections at the rear of the instrument (particular the mains plug) against contamination.

Although constructional measures have been designed to virtually eliminate such a situation, should corrosive media penetrate the interior of the instruments the mains plug of the 793 IC Sample Prep Module must be immediately disconnected to prevent extensive damage to the instrument electronics. Inform Metrohm service if your instrument has been damaged in such a way.

The instrument must not be opened by untrained personnel. Please comply with the safety notes in section 1.4.1.

4.2.2 Maintenance by Metrohm service

Maintenance of the 793 IC Sample Prep Module is best done as part of an annual service performed by specialists from the Metrohm company. Due to caustic and corrosive chemicals which are processed by this device, it may be necessary to shorten the interval between servicing.

The Metrohm service department is always willing to offer expert advice on the maintenance and servicing of all Metrohm instruments.

4.2.3 Shutdown

If the IC system is shut down for a considerable length of time, the entire IC system (without rinsed free from salt with methanol/water (1:4) to avoid crystallization of eluent salts with the corresponding subsequent damage. In order to rinse them the separating column, suppressor and actuator are disconnected and the injector and detector are directly connected to each other.

4.2 Maintenance and servicing

4.2.4 Exchanging the pump tubing

Pump tubings are consumable material with a limited lifetime and should be exchanged at regular intervals (approx. every 4 weeks under continuous use).

The working life of pump tubing depends to a considerable extent on the contact pressure. This is why the contact pressure must be correctly set as described in section 2.3.2 or 2.4.2 respectively. If the pump is to remain switched off for a lengthy period of time the tubing cartridges should be raised completely by loosening snap-action lever 10 right-hand side (the set contact pressure remains unchanged).

As the pump is always operated on the same side the pump tubings

6.1826.010 supplied can be used on both sides. To exchange a pump tubing proceed as follows:

1 Remove old pump tubing

4.2.5 Regeneration of the cation exchange material

If the actuator units are exposed to certain heavy metals (e.g. iron) or organic contaminants for longer periods of time then these can no longer be removed completely by the regeneration solution normally used (20 mmol/L HClO such capacity problems occur then the actuator units must be treated as follows:

1 Disconnect SP Module A from IC system

2 Regenerate cation exchange material

x Rinse all 3 actuator units one after another for about 10 min

with one of the following solutions:

For heavy metal contamination

0.2 mol/L HClO + 0.1 mol/L oxalic acid (in case of Fe+2/Fe+3)

For contamination with organic substances

0.2 mol/L HClO

The 6.1826.010 Pump tubing is made of PVC and must not be used for rinsing with solutions which contain acetone. In such cases a different pump tubing or a different pump (e.g. 709 IC Pump) must be used for rinsing purposes.

For day and night operation the warranty is limited to 6 months.

Glass breakage in the case of electrodes or other parts is not covered by the warranty. Checks which we are asked to carry out during the warranty period for reasons other than material or manufacturing faults will be invoiced. For parts manufactured by third parties, insofar as these constitute an appreciable part of our instrument, the warranty stipulations of the manufacturer in question apply.

With the regard to the guarantee of accuracy, the technical specifications in the instruction manual are authoritative.

With regard to defects in material, construction or design as well as the absence of guaranteed features, the purchaser has no rights or claims except those mentioned above.

If damage of the packaging is evident on receipt of a consignment or if the goods show signs of transport damage after unpacking, the carrier must be informed immediately and a written damage report demanded. Lack of an official damage report releases Metrohm from any liability to pay compensation.

If any instruments and parts have to be returned, the original packaging should be used if at all possible. This applies above all to instruments, electrodes, burette cylinders and PTFE pistons. Before embedding them in wood shavings or similar material, the parts must be packed in a dustproof package (for instruments the use of a plastic bag is imperative). If open assemblies are enclosed in the scope of delivery that are sensitive to electromagnetic voltages (e.g. data interfaces etc.) these must be returned in the associated original protective packaging (e.g. conductive protective bag).
