PAL RSI: Workhorse for analytical labs

The PAL RSI is the robust workhorse for analytical labs. It is the cost effective solution for labs in need of robustness and uncompromising performance.

Scientists and technicians work under time pressure and often with a tremendous workload. The reliability of hardware and software should not be something the user has to worry about. Reliability is just expected from every tool.

That is exactly what the PAL RSI is designed for. It is a tool that you can rely on. More than 40.000 PAL systems worldwide are proof of this. Every PAL RSI leaving our factory has passed a thorough robustness test.

The PAL RSI is a flexible tool. Its open and modular architecture makes it the most versatile system on the market. Tools can be exchanged readily within minutes.

PAL customers working with GC love the possibility to use liquid, headspace or SPME sampling on the same system. LC customers appreciate the PAL because of its huge sample capacity, the range of syringes and valves available.

The PAL RSI is a safe investment: if your requirements grow additions of modules or even an upgrade to the full RTC functionality are possible at any time and give access to complete workflow automation.


Tools and benifits

Increased Vial Capacity

  • 162 x 2mL or 60 x 10mL or 20mL vials/tray holder, other vial types and microtiter plates can be handled
  • With temperature controlled stacks a maximum of 9216 samples out of 24 MTP's can be handled
  • Cooled Stack with position control
CTC RTC Vial-Capacity

Minimized carryover and reproducible injection of minute sample volumes

  • Bottom sensing makes sure that small volumes can be injected out of a few µL of sample (e.g. 3 x 1 µL out of 5 µL).
  • With Constant Force Technology the PAL detects the correct position of the needle in the specially designed needle seal. Potential carryover is avoided
CTC RTC Minimum-carryover

Process Safety

  • Position detection means process safety. Missing vials or the correct position of the injector are detected and traced.
  • Position detection for the temperature controlled stack ensures that the drawer is in the correct position (open / closed) and the temperature is monitored.

Discrimination free GC Injection

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