Overview
A sample application can perform Headspace Analysis using 10ml or 20 ml vials. The process will use a vent tool to flush the headspace of the sample vial prior to each injection. This flushing of an inert gas can be followed by an agitation period during which the vial will be heated and shaken in an agitator. The length of the flush period as well as the agitation period will be determined by the operator. Once the agitation process is completed, a headspace sample will be collected from the vial and injected into the appropriate GC port for analysis.
Main Features
- Works with standard COMBI PAL
- Dynamic Headspace analysis
- Multiple Headspace Extraction
- Analysis which require removal of ambient air from headspace
- Large volume dispensing to closed vials
- Can provide pressure relief
Requirements
- COMBI PAL with gas flush line and magnetic transportation of vials
- Special PAL firmware supplied by LEAP
- Special macro or cycle required and supplied by LEAP
- Vials must have thin piercable septa
Uses include
- Headspace stripping
- Relief of pressure from reactions
- Both positive and negative
- Relief of pressure from large volume additions
- Replacement of gases within a vial
- Multiple Headspace Extraction – an integration technique for quantifying how much of each compound is in a sample
- Blanketing the sample with an inert gas, i.e. foods, so that no oxidation takes place in the headspace while the sample is being heated

LEAP strives to find total solutions for analytical lab automation by automating analytical processes for small and large molecules in extracted liquids, solids, and recently in human, animal and plant tissues. We provide the precise robotics and efficient sample prep required by modern measurement techniques such as MALDITOF mass spectroscopy. Our newest specialty customization of CTC Analytics’ PAL features small workstations that can perform complex liquid handling tasks including HPLC-Purification, SPE, filtration, weighing, heating and stirring. They can be configured as stand alone units or integrated for “just in time” sample prep for LC-MS or GC-MS analysis.
LEAP provides automated workstation instrumentation solutions based on the LEAP CTC PAL X, Y, Z syringe only autosampler robot from LEAP Technologies. This extremely flexible, precise, and adaptable liquid handling robotic platform is available in a variety of lengths and options depending on the requirements of your sample preparation and injections for your UHPLC, LC or GC chromatography.LEAP offers full support and service for the PAL platform in addition to being able to write custom macros, cycles, and scheduling to your applications. Please contact LEAP Technologies on how we can help you get maximized throughput with flexible pipetting automation solutions.
