Abstract Headspace Analyzer
A simple and fairly standardized technique of extracting volatile and semi-volatile substances from raw samples in liquid or solid form is headspace analyzes . 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 COMBI PAL performs all the tasks for this extraction method unattended. For a sequence of samples up to 96 the COMBI PAL 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)are the tools that can be mounted in the injection head.

More than just an autoinjector, the LEAP Prep and Load (PAL) system is a sample preparation system that can perform a variety of preparation steps while integrating seamlessly with your GC & GCMS, or LC & LCMS via hardware adaptations and software drivers. GC uses include headspace, direct injection, SPME, ITEX, derivatization, dilutions and much more. HPLC uses include dilutions, incubations, filtration, weighing, heating, cooling, timed sequences, MALDI spotting, SPE and much more. The sample capacity of the PAL systems exceed most autoinjectors on the market today offering greater walk-away capability and far more power to prepare your samples. The PAL is also capable of operating as a stand-alone workstation, offering countless automation possibilities for your lab....

LEAP Technologies provides fully automated sample processing workstation instrumentation solutions based on the LEAP CTC PAL X, Y, Z syringe only autosampler robot. 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 also offers process control systems and stand alone workstations. LEAP is an open, neutral resource for technical support of existing PAL. Keep your PAL in peak working order LEAP offers full support and service for the PAL platform with over 11 years of history with the PAL. LEAP can also write custom macros, cycles, and scheduling software for your specific applications. We're proud that LEAP is known as a productivity improver for laboratories including 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. LEAP can help to keep them running and analyze samples around the clock. LEAP has most of its laboratory automation robots under GSAcontract and is eager to service and maintain everything it sells to keep your expensive lab equipment running around the clock. CTC Analytics Combi PAL and HTS PAL for Front-End Automation for LC and GC applications. LEAP offers customized on-site training. LEAP Is continuing to develop FAQ, Solutions, Tips & Techniques,a Learning Center with the LEAP Wiki for the benefit of all PAL Platform Robotic users. We will continue exceeding customer expectations for quality, cost effective and efficient results using the most current technology and expertise in our industry. Our aim is to be the ultimate knowledge base on everything related to the PAL. LEAP is known as the autosamplerguys being in business over twenty years. LEAP has extensive multi-vendor experience with integrating the PAL. HTX, HTS, HTC, HTX-xt, HTS-xt, HTC-xt, LC-Mini, Combi PAL,COMBI-xt PAL, and GC PAL models. We have the Quality, Training, Parts availability, Infrastructure, and Experience.LEAP is sometimes referred to as an Application Automation House who is continually adding new products and solutions to its Lab Automation line.
