MultiSwitch

Column Selection - Ambient Temperature

Fully Automated

Column Selection for up tp 10

HPLC/UHPLC Columns

MultiSwitch Column Selector

The MultiSwitch column selector designed for fully automated selection for up to 10 HPLC or UHPLC columns (up to 15kpsi) or for 6 UHPLC columns (up to 20000 psi) under ambient temperature. The system consists of two MayLab MS 5000 valve drives, the MS 6000 NG interface, a robust rack for the MS 6000 NG valve drives and a “snap in” column holder for 4, 6, 8 or 10 columns depending on version.

Software drivers for chromatography data systems must be ordered separately.

MultiSwitch Features Summary

Robust column holder for 4, 6, 8 or 10 columns each 300 mm * 4,6mm
Easy assembly of fittings and capillaries through removable valve drives
Valve switching speed less than 100 ms
Patented microprocessor controlled valve actuating
RS 232 or USB control
Very rugged, reliable and laboratory proven construction
Drill Holes for Bench top mounting

MultiSwitch Interfacing
Chromatography Data Systems

Fully automated column selection within a chromatography data system is the most efficient way for unattended and overnight operation when using different methods with different columns under ambient temperature.

Software drivers are available for:

Agilent ChemStation 16 bit and 32 bit
Agilent EZChrom Elite V 3.1.4 and higher
Dionex Chromeleon V 6.4 and higher
AB Sciex Analyst V 1.4.1 and higher (tested up to version 1.7)
Thermo Scientific ChomQuest V 4.1 and higher
Thermo Scientific Xcalibur V 1.4 and higher (tested up to version 4.0)
Agilent EZChrom Elite V 3.1.4 and higher

The drivers named above are designed to report every error (e.g. faulty valve)

through message boxes and will stop the actual running method immediately.

MultiSwitch NG and GLP

(Good Laboratory Practice)

Both MS 6000 NG valve drives are selecting the column at exactly the same time. The actual column position is constantly being reported to the MS 6000 NG Interface and to the driver software. Each switching cycle is recorded in a log file, including action, time and date stamp due to GLP reasons for each day. By this means the systems activities will be manageable and reproducible for the operator.

MultiSwitch NG and Valve Configuration

For column selection two of the approved VICI Cheminert high (up to 5000 psi) or ultra high (up to 20000psi) pressure valves with 1/16” fittings and 0.25 mm or 0.4 mm port diameter are used in combination with two MayLab MS 6000 NG valve drives and the MS 6000 NG Interface in synchronous operation.
This unique column selection on the column in and output decreases carry over and increases the system´s performance.

The MultiSwitch NG system solution is available for selecting 4, 6, 8 or 10 HPLC columns for up to 5000psi.

For pressures up to 15000psi or 20000psi a 6 column selector is available.
The 10 column UHPLC selector can be operated up to 15.000psi
