There are many techniques and applications that LEAP can help you with to increase sample throughput with automated injection HPLC[http://leapwiki.com/mediawiki/index.php?title=Category:HPLC] and UPLC[http://www.leapwiki.com/mediawiki/index.php?title=UPLC] systems. From "Front Cuts"[http://www.leapwiki.com/mediawiki/index.php?title=Category:Frontcut] to "Heart Cuts"[http://www.leapwiki.com/mediawiki/index.php?title=Category:Heart_Cut] to "Back Cuts"[http://www.leapwiki.com/mediawiki/index.php?title=Category:Backcut] to "Multiplexing"[http://www.leapwiki.com/mediawiki/index.php?title=Category:Multiplexing]. Typical applications are pre-column SPE, pre-column cleanup, sample desalting,parallel column regeneration[http://www.leapwiki.com/mediawiki/index.php?title=Category:Regeneration], etc. LEAP has the experience to solve your throughput needs. These are just a few of our offerings. We integrate multiple vendors HPLC systems and have a wide array of injection valves and selector valves to get you the best result. Many of these can be added to your existing systems to better utilize the hardware you already have with some additional valve switching modules[http://www.leapwiki.com/mediawiki/index.php?title=Valve_Switching_Modules] from LEAP.

[http://www.leaptec.com/ LEAP Technologies] provides fully automated sample processing workstation instrumentation solutions based on the LEAP CTC [http://leapwiki.com/mediawiki/index.php?title=Category:PAL 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 [http://www.leapwiki.com/mediawiki/index.php?title=Category:Service support and service] for the PAL platform with over 11 years of history with the PAL. LEAP can also write custom macros, [http://www.leapwiki.com/mediawiki/index.php?title=Category:Cycles cycles], and scheduling [http://www.leapwiki.com/mediawiki/index.php?title=Category:Software 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 [http://leapwiki.com/mediawiki/index.php?title=Category:GSA GSA]contract 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. As we do so we change the content of this web site so please check back.<br>Please contact LEAP Technologies on how we can help you get maximized throughput with flexible pipetting automation solutions whether it is our standard applications or customized to your needs. The Combi-xt PAL autosampler is able to perform liquid and headspace analysis. Headspace options include Solid Phase Micro-extraction (SPME) and ITEX-2 as alternative to purge and trap. The HTS-xt PAL autosampler dramatically increases sample throughput by offering automated sample prep, Peltier cooled and heated sample storage using the cooled stack, Peltier cooled and heated sample storage using the cooled stack and low carryover due to the self-cleaning DLW (Dynamic Load and Wash) module and L-Mark syringes, peltier cooled valves and columns.  LEAP provides automation that fits your needs and reduces errors, increases sample capacity, increases efficiency, reduces cost by supplying long term productivity improvements with user friendly software and flexible hardware. LEAP performs just in time or on time sample prep and inject. LEAP offers full support of integrated and non-integrated PAL software with both sales and support for Cruise Control, Cycle Composer and Cycle Composer Macro Editor, Agilent ChemStation CTC Control, Mass Hunter and EZChrom CTC integration, Xcalibur, Waters Masslynx or Analyst CTC Control software, Thermo (Finnegan) XCalibur, LEAP Shell, and Chronos software. The PAL is more than just an autosampler, it is a high-quality and efficient laboratory robot platform that can be customized by LEAP Technologies to meet your specific needs.

Specific Categories

There are many techniques and applications that LEAP Technologies can help you with to increase sample throughput with automated injection HPLC and UPLC systems. From "Front Cuts" to "Heart Cuts" to "Back Cuts" to "Multiplexing". Typical applications are pre-column SPE, pre-column cleanup, sample desalting,parallel column regeneration, etc. LEAP has the experience to solve your throughput needs. These are just a few of our offerings. We integrate multiple vendors HPLC systems and have a wide array of injection valves and selector valves to get you the best result. Many of these can be added to your existing systems to better utilize the hardware you already have with some additional valve switching modules from LEAP Technologies.

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.
