Overview
ITSP (Instrument Top Sample Prep) for Serial Solid Phase Extraction (SPE) or Sample Filtration uses a standard PAL syringe as the solvent reservoir for Microliter's disposable SPE cartridges. The combination replaces expensive dedicated SPE liquid handlers and cumbersome or inconsistent vacuum manifolds. Pressurizing multiple wells is eliminated, no loss of samples or inconsistency of extraction due to leaks or loss of vacuum. Furthermore standard SPE liquid handlers require a manual transfer of the extracted samples to a sample injector. Since the PAL itself is a sample injector this can be avoided using the automated ITSP – PAL combination.
Significant Markets
Any labs who are doing High Performance Liquid Chromatography (HPLC) or more significantly, Ultra High Performance Liquid Chromatography (UHPLC) analysis. It is imperative that particles are eliminated to avoid blockage of HPLC lines and columns.
How it works by Microliter
ITSP (Instrument Top Sample Prep) is a consumable device that allows for a common autosampler used on most chromatographs to prepare client samples using Solid Phase Extraction (SPE) or filtration. ITSP’s septum seals and grips the needle creating a closed environment above the bedmass. By removing the volume above the column bedmass and replacing it with the analytical instrument’s syringe, solutions can be passed across the bedmass using the hydraulic pressure of the syringe plunger. The gripping action of the septum also allows for the ITSP device to be transported to any location on the autosampler. By defining waste and elution locations the device can be prepped in one location and moved to elute the collected compounds in another. Once eluted into a clean receptacle the instrument can discard the device and inject the eluate onto the analytical instrument.
The following diagrams illustrate the ITSP device and the typical set-up on an LC/MS/MS autosampler.
