Valve Switching Modules |
Valve Switching Modules for the PAL consist of 2 or 3 individually controlled multi-position valve drives arranged in a vertical stack. The top valve acts usually as injection valve, while the remaining one or two valves are used as switching valves. Typical applications are pre-column SPE, pre-column cleanup, sample desalting, etc. For increased sample throughput the accessory can be used for time staggered "heart-cuts"[1] of two independent gradient systems. Important chromatogram parts only reach the detector just in time using a selector valve, while the front-[2] and end-cut[3]goes to waste. The compact valve module arrangement results in a space saving setup with very short connection lines. The modules are compatible either with 4- 6- 8- or 10-port valves and can be mixed on the same valve drive module.
- Pre-column sample cleanup, desalting or pre-column SPE
- Alternate column regeneration
- 4 - 6 - 8 - or 10 - port valves individually arranged in a vertical stack
