Measuring nicotine partitioning from a tobacco smoke filter pad in an ammonia environment
A Twin PAL  is used to measure nicotine partitioning from a tobacco smoke filter pad in an ammonia environment.
Filter pads that have collected tobacco smoke will be placed in 20ml vials. A zero-analysis will be performed by the SPME PAL.
Then the Prep injection head will add 5 to 40mls  of ammonia to the sample vial using a 5ml syringe and the vent tool.
After the sample equilibrates, the sample vial will be placed in the agitator  and SPME  analysis will be performed.
This process of flushing the sample vial with ammonia and then performing SPME  analysis will be repeated for a number of iterations determined by the operator.

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.
