PAL System

Prep and Load Platform

The new Generation PAL LSI, PAL RSI and PAL RTC


Choose, then configure your PAL for the jobs you want done.


PAL RTC Highest Productivity

The PAL RTC with Robotic Tool Change is the logical (r)evolution of the successful PAL-xt product line. It is a robotic platform for the efficient and safe automation of most sample preparation steps.

The robotic change of tools enables unattended 24/7 operation, even for multistep workflows and thereby greatly increases the productivity of labs. At the same time process safety is optimized since all operations become traceable.


PAL RSI Workhorse for Sample Prep

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

The PAL RSI is a safe investment: if your requirements grow an upgrade to the full RTC functionality is possible and gives access to complete workflow automation.


PAL LSI Robust and Reliable Sample Handling

The PAL LSI is an economical system designed for the accurate and precise handling of gaseous and liquid samples.

PAL Sample Control Software for

Efficient Operation of PAL RTC & RSI The latest generation of PALs can all be controlled by the user friendly PAL Sample Control sof tware. It interfaces seamlessly with many common CDS and MS-data systems (e.g. AB Sciex Analyst, Agilent Chemstation, Masshunter oder Thermo Scientific Xcalibur). With a few clicks you can import or generate sample lists and start the data acquisition. Or you can quickly set up workflows to eliminate tedious manual operations. PAL Sample Control allows overlapping of time consuming steps. This increases sample throughput greatly and boosts productivity.

The PAL LSI Robust and Reliable Sample Handling


The PAL LSI is an economical system designed for the accurate and precise handling of gaseous and liquid samples.


The PAL LSI can move objects, like vials from and to any position within its working range

The PAL LSI is available as compact or standard sized system

The PAL LSI, like all members of the PAL family it can be upgraded should the need arise for more functionality or sample capacity 

PAL LSI: Innovative features giving real benefits


Perfect injection handling gives reproducible results
Only perfect injection handling gives reproducible results.
The PAL LSI is designed for the precise and accurate handling of liquid and gaseous 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 examples highlighted here 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.

The PAL RSI is the reliable and flexible workhorse for todays analytical labs


Ingeniously reliable.

Laboratories 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 was designed for. It is a tool that you can rely on. 40.000 PAL systems worldwide are proof of this. Every PAL RSI leaving our factory has passed a 24 h robustness test.

The PAL RSI defines the industry standard for intelligent sample preparation and is the most flexible system on the market.


The 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 use the PAL because of its huge sample capacity, the range of syringes and valves available.

The PAL RTC is all about increasing productivity.


Automation is the way to increase productivity and (process) safety in the laboratory. Transferring repetitive or dangerous manual tasks to a robot improves safety. The possibility to run the instrument 24h/day increases

throughput, especially for long sample preparations.


The PAL RTC was developed to maximize productivity in analytical and clinical labs. Robotic Tool Change (RTC) brings sample preparation to a higher level. Every process requires a number of different tools for best performance,

e.g. a 10ÁL syringe for the accurate addition of small volumes followed by the dilution with a 1mL syringe. Robotic Tool Change allows to switch between different tools automatically.


This additional versatility in combination with the large number of available tools enable the design of tailored automation processes.

Robotic Tool Change takes productivity to a new level.


Ingeniously productive.


  • Automatic selection of the syringe with optimal accuracy for adding standards or preparing serial dilutions
  • On the fly switching between a syringe tool for the addition of an internal standard and the LC/MS Tool for subsequent analysis
  • Possibility to permanently configure several workflows on one system for a walk-up prep station, e.g. Liquid/Liquid Extraction and Solid Phase Extraction (SPE)
  • Automated optimization of methods e.g. by selecting the most suitable Solid Phase Micro Extraction (SPME) fiber from an array of 4 different ones
  • Derivatization reactions performed without manual intervention for productivity, protection against hazardous chemicals and process safety
  • Automation of labor intensive manual workflows like
  • protein digestion
