Verification of devices
The second-hand devices are verified by Labexchange Service GmbH before delivery. You are receiving only fully functional devices.
Dispatch time
The stated dispatch times are the shortest possible ones for each article. The effective dispatch times can vary. The effective dispatch times will be stated in the order confirmation.
As a matter of principle, we are offering collective deliveries. The shipping time is calculated based on the position with the longest lead time. A partial delivery is possible on explicit request.
Shipping methods
Parcel services, forwarding agencies, self-pickup, delivery by Labexchange fleet.
Delivery information
Prices exclude shipping costs. Stated shipping costs are to be expected. Deviations are possible. If transport costs are not specified, please ask separately for them.
The stated transport and packing charges apply to the most favorable route if transport and are to be understood as subject to verification due to unexpected cost increases. By reason of unpredictable events, cargo rates and delivery times can change at any time and therefore have to be adapted to the recent situation. Import formalities and possible customs charges will be borne by the purchaser. Incoterm coding according to Incoterms 2010: For persons who collect the devices themselves: EXW, for dipatch by sea: CFR, by air freight: CPT, other shipments: DAP. Note for international shipments: A proof of preference/EUR1 will not be issued by us. When self-collecting/ordering EXW from countries within or outside the European Union, 16% VAT will be retained as a deposit until we have received the corresponding confirmation of arrival/bill of delivery from the buyer.
Terms of payment
We do not accept payment by letter of credit, PayPal, etc. In each case the invoice amount is payable without deduction. Discount is not granted.

General Operating Instructions
The Fast Sep Cation II is used with the Fast Sep Cation I in the Column Switching Mode to obtain the fastest possible results for the simultaneous analysis of both alkali and alkaline earth metals under isocratic eluant conditions. Figure 3-1 is a representation of the separation scheme.
Fig. 3-1 Representation of an Analysis Using Column Switching between the Fast Sep Cation I and II columns
When the sample is injected, the column switching valve should be in the OFF position: the eluant flows first through the Fast Sep Cation II column and then through the Cation I column. The divalent cations in the sample will be retained by the Cation Il column, while the monovalent cations are essentially unretained by this column and move to the Cation I column where they are separated.
At 40 seconds (0.6 min.) after injection the valve is switched ON. The eluant now flows first through the cation I column and then through the Cation II column. This prevents the divalent cations in the sample from going through the Cation I column, providing rapid divalent cations separation by the Cation II column.
If you have a Gradient Pump Module (GPM), you can control the injection valve and the column switching valve automatically through GPM valves 5 and 6, respectively. The program would be as follows:

GENERAL OPERATING CONDITIONS
Eluant components: HCI and 2,3-diaminopropionic acid monohydrochloride (DAP.HCI) Eluant flow rate: 2.0 mL/minute
Regenerant: 0.1 M tetrabutylammoniumhydroxide (TBAOH)
Regenerant flow rate: greater or equal to 5 mL/minute
Detector Range: 10 µS full scale or as required
Sample loop: 50 µL (or as required)
CHEMICALS REQUIRED
It is very important for the eluant to be as free of metalic impurities as possible. Thus, chemicals and water used should be of the greatest available purity.
Only use concentrated HCI, Ultrex grade or Baker Instra-Analyzed for Trace Metals.
Use DL-2,3-Diaminopropionic acid monohydrochloride (DAP.HCI) from Fluka Chemical Corporation ONLY
Use Dionex Tetrabutylammonium hydroxide (TBAOH), 0.1 M (P/N 39602)
Use deionized water, 18 MOhm or better.
SYSTEM REQUIREMENTS
The Anion MicroMembrane Suppressor (AMMS-1) is designed to be run on a Series 2000i or 4000i Ion Chromatograph (IC) equipped with an anion exchange column set and a Conductivity Detector Module (CDM). The Anion MicroMembrane Suppressor (AMMS-1) is installed immediately after the analytical column and before the conductivity detector in the column compartment of the chromatography module.
INTRODUCTION TO ANION ANALYSIS ELUENT SUPPRESSION
The Anion MicroMembrane Suppressors, AMMS-II and AMMS (2mm) provide high capacity suppression while adding a minimum of dead volume to the analytical system. The AMMS (2mm) is specially designed to be used with 2mm ion chromatography columns and is only compatible with 2mm chromatography systems. Its equivalent suppression capacity is greater than the suppression capacity achieved in the Anion MicroMembrane Suppressor used with 4mm ion chromatography column systems (AMMS-11). The ability of the AMMS-II and AMMS (2mm), to provide continuous suppression of traditional eluents, as well as eluents as concentrated as 0.1 M NaOH, significantly expands the capabilities of anion exchange ion chromatography.
