Original tobacco samples will be placed in 20ml vials. These vials will be loaded into a shaker tray that will also heat and agitate the samples at the appropriate time. The PAL will 15ml of solvent will be added to each sample in the batch. Then 50ul of internal standard will also be added to each sample in the batch. After these two additions, the samples will be heated and agitated for a period of time specified by the user. Once the incubation period expires, 1.5ml of each sample will be filtered through a 0.45 micron PTFE filter. Then 1ml of each filtered sample will be transferred to a separate 2ml vial for off-line analysis.

For other cost/time saving measures consider:
- LEAP offers multiple choices of Valve Self Wash Stations to aid in cleaning the valve [1]
- Dual Channel Serial Injection with Front Cut (M-002) using Analyst and ICC-CE [2]
- Dual Channel Parallel Injection (M-003) using Cycle Composer Software and Analyst [3]
- “Look Ahead”, sample prep before injection (M-004) using LEAP Shell Software [4]
- Dual Channel Parallel Injection (M-005) using LEAP Shell software [5]
- Summary of LC Multi Valve Applications [6]
- LEAP Shell Software and application for custom injections and scheduling [7]
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.
