The O.I. Analytical Model 4560 Sample Concentrator thermally traps and desorbs organic compounds for GC and GC/MS analysis.
The Model 4560 Purge-and-Trap Sample Concentrator collects and transfers volatile organic compounds to a GC or GC/MS for analysis. It is specifically designed to purge volatiles from water, soil, and air for concentration onto a sorbent trap in compliance with USEPA protocol. The sample transfer line connects directly to the column or through an optional Low-Dead-Volume InjectorTM to the GC column in an analytical system.
Features:
• Built-in Cyclone Water ManagementTM minimizes the amount of water transferred to the analytical column and detector.
• Uses 5- and 25-mL frit and needle spargers and disposable tube spargers, using the same length needle and “wide-neck” 18-mm mount.
• Handles sample foaming and spillover through a removable particle foam filter in the sample inlet.
• Provides controlled temperature of each heated zone.
• Processor-controlled and fully interactive via the RS-232-C communication port.
• Basic operational sequence is controlled by key entry; operator interface is simple to use and vacuum-fluorescent display is easy to read. 2 Model 4560 Sample Concentrator Operator’s Manual Rev. 2.3
• Up to 14 sets of run settings can be saved, loaded as files, and even sequenced during a multisampler run.
• Rapid trap heating (900°C/min) and cooling (250°C/min) optimizes chromatography and reduces run times.
• All lines contacting the sample are inert and impermeable to gases.
• Incorporates power-up self-test and diagnostics messages.
• Optional Internal Carrier Flow Controller allows all gases (purge and carrier) to be provided by and monitored through the sample concentrator.
• Incorporates BCD inputs for multisampler position monitoring.
