MultiSwitch System Solution

The MultiSwitch system solution is 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 5000 interface, a robust rack for the MS 5000 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
  • Thermo Scientific ChomQuest V 4.1 and higher
  • Thermo Scientific Xcalibur V 1.4 and higher
  • 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 and GLP (Good Laboratory Practice)

Both MS 5000 valve drives are selecting the column at exactly the same time. The actual column position is constantly being reported to the MS 5000 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 and Valve Configurations

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 5000 valve drives and the MS 5000 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 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.

 

Included in Delivery

  • MS 5000 Interface (Column selection controller)
  • PEEK or Stainless Steel Fittings for VICI Cheminert valve (depending on valve type)
  • RS 232 cable for connecting MS 5000 interface to PC
  • Cables for connecting the MS 5000 valve drives to MS 5000 interface
  • Instruction Manual
