Abstract
A simple and fairly standardized technique of extracting volatile and semi-volatile substances from raw samples in liquid or solid form is headspace analyzes [1]. A sample is placed in a vial that is sealed by a septum and cap and heated in an incubator for a specific time. Once the content of the vial has reached equilibrium a sampled is extracted and injected into the injection port of a GC. LEAP’s specific equipment the CTC CombiPAL[2] performs all the tasks for this extraction method unattended. For a sequence of samples up to 96 the Combi PAL[3] will schedule the vials to be in the incubator/agitator for the same amount of time before a precise sample of headspace gas is extracted by a heated syringe system for a subsequent appropriate injection into a GC. Many variables are programmable over a validated range. 1ml, 2.5ml and 5ml syringes and a solvent-less solid phase micro extraction system (SPME)[4]are the tools that can be mounted in the injection head.

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. We're proud that LEAP is known as a productivity improver for laboratories, and we have big plans to even make government labs in agencies such as FDA, USDA, EPA, FBI, Armed Forces, Homeland Security and others function more efficiently. Robotic sample prep equipment works well in government labs and challenges lab technicians to keep feeding those more samples. Analytical equipment such as chromatographs and mass spectrometers are expensive devices and also expensive to maintain. The least an owner can do is to keep them running and analyze samples around the clock. LEAP has most of its lab automation robots under GSA contract and is eager to service and maintain everything it sells to keep your expensive lab equipment running around the clock. Please contact LEAP Technologies on how we can help you get maximized throughput with flexible pipetting automation solutions
