PAL LSI: Robust and reliable sample handling

Reproducible results thanks to optimized injection handling

Only perfect injection handling gives reproducible results. The PAL LSI is designed for the precise and accurate handling of liquid samples of up to 100 µL in volume. In combination with the PAL Sample Control software all parameters of aspirating and dispensing of liquid samples can be fully controlled. This is crucial for perfect injections. A range of syringes from 1.2 µL to 100 µL is available. In the example highlighted above an aliquot of an internal standard is sandwiched between transport solvent and the sample. Air gaps in between the liquids preclude mixing of the different liquids. The accurate control of these steps is the basis of reproducible methods.

Pick and place

The PAL LSI is a robot that can reach any three dimensional position within its working space and is ideally suited to pick and place objects like vials. It can inject from several sample containers into different detectors or transport vials from a tray to a temperature controlled stack.

Enhanced productivity due to innovative features

Easy maintance and adaption

The different syringes available (1.2 / 5 / 10 / 25 and 100 µL) can readily be exchanged within seconds.

Large Sample Capacity

162 x 2 mL-vials can be stored on one tray holder. The standard length PAL LSI can hold 648 x 2 mL-vials on four Tray Holders. With the optional Peltier stack samples can be stored at a controlled temperature.

CTC RTC Vial-Capacity

Process Safety

Proprietary drive technology enables the detection of missing vials and the correct position of the syringe needle in the injector port. Bending of syringe needles is excluded.

Ultrafast injections

Injections down to 100 ms reduce discrimination in GC down to C40/C20 > 0.98.
