40'000 systems are proof of its reliability and flexibility. PAL Systems increase productivity in labs and greatly improve traceability, worldwide.
The PAL System is the basis for precise and accurate handling of gaseous and liquid samples.
Ingeniously reliable, flexible and productive.

The PAL RTC with Robotic Tool Change is the logical (r)evolution of the successful PAL-xt product line. Sample prep for chromatography is no longer  the bottleneck – automate your sample prep and sample injection - all on the PAL RTC.

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.

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 10µL 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.

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. 

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.

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.

Time is money. To maximize productivity the PAL DHR performs tasks with two heads in parallel:

  • Two heads can move independently
  • The heads can execute two independent workflows:
    - Headspace with sample preparation, e.g. standard addition or derivatization
    - High throughput parallel injections into two GC- or LC-systems
  • The software optimizes the timetable to maximize productivity
  • Automatic collision control ensures process safety and easy programming
  • 120 or 160 cm wide working area
  • Combinations of RTC/RSI heads
  • With an RTC head tool change expands the options further

PAL Consumables

The PAL SPME Arrow (patent pending) is a new technology for microextraction, combining trace level sensitivity (up to 10x higher) with high mechanical robustness (at least 2x longer lifetime). The PAL SPME Arrow has an outer diameter of 1.1 or 1.5mm, resulting in large sorption phase surfaces and volumes. The arrow-shaped tip allows smooth penetration of vial and injector septa. In contrast to traditional SPME fibers, the Arrow design fully protects the sorptive material, minimizing adverse influences and loss of analytes during transfer processes. 

PAL SPME Fibers have been developed and optimized for the most successful SPME sampler, the PAL System Autosampler. The fibers are offered with different coatings and film thicknesses (PAL SPME Fiber brochure). Their excellent extraction properties have been demonstrated for important applications and are compared to fibers available in the market (PAL SPME Fiber Comparison). 

  • Designed for our new PAL3-Decapper Tool
  • Better sealing due to flat finish of contact surface to septum
  • Easy access to last drops due to slightly curved inner bottom shape
  • PAL System tested and approved
