Combi PAL
Performs injections into GCs as liquids or generates head space gas extractions in an agitator/heater combination before gas injections. Loading vials into the incubator is precisely timed that all samples experience the exact same incubation time and the preparation step is completely synchronized with the injection and analysis time. The result is a highest possible throughput and exactly reproduced prep steps for each sample.
A very popular option is the SPME fiber for solvent-less extractions and the barcode option. Also popular are microtiter plates from where all PALs can sample.
The CombiPAL from LEAP Technologies is the most versatile headspace autosampler on the market. No other device performs the three major static headspace injections, and offers macro enabled procedures for Multiple Headspace Extraction (MHE), sampler preparation, and dynamic headspace injections (via the ITEX injection head).
- Static Headspace, Liquid Injection and SPME (Solid Phase Micro Extraction) combined in one instrument
- Upgrade in 2 steps from a Combi PAL basic version to Headspace and / or SPME operation
- Top mounted on GC's, saves valuable bench space
- Syringe only concept for transparent sample operation, no sample loops, transfer lines, or switching valves
- Interfaces with any major GC/GC-MS system
- Remote control software for customized prep and load cycles
With the syringe only concept of the Combi PAL a headspace technology has been introduced to eliminate the headaches commonly associated with conventional autosamplers. The robotic vial processing operation allows sample analysis in a straightforward and simple way. Sample vials are transported into the heated six position incubator for preconditioning. After reaching the equilibration, a heated gas-tight syringe is moved over the incubator and the headspace sample is withdrawn. After sample injection the hot syringe is automatically cleaned by purging with inert gas. No complicated error prone operations e.g. vial pressurization, valve switching, loop filling or heated transfer lines are involved. For maximum throughput, the intelligently controlled vial transfer into the incubator oven ensures that a sample is always ready to be injected when the previous run is completed. Beside the simple and transparent sample operation the COMBI PAL offers even more advantages over conventional headspace sampling eliminates dead volume and adsorption effect in sample loops and transfer lines permits adjustable sample volumes without sample loop changes no sample dilution due to vial pressurization.
At this point of time the COMBI PAL remains to be the most flexible and versatile GC Autosampler in the industry:
- True X/Y/Z Autosampler for high speed sampling and sample prep.
- Optional Headspace, SPME and ITEX mode to cope with all types of sampling (not just liquids)
- Buy a Headspace Autosampler and get Liquid Injection for free. It is an investment that will grow with all of your needs.
- Built-in Intelligence and Sample Prep. The PAL has been designed for Sample Prep from the beginning. Liquid injection and liquid handling is just one of the features.
- Highest Sample Capacity in Liquid and Headspace Mode
- Compatible with all GC platforms
- Top mounted design saves bench space
The initial costs of the other auto samplers maybe slightly lower than a COMBI PAL Liquid Sampler version, but the additional flexibility of the COMBI PAL will make the PAL the instrument of choice in most cases. The Total Cost of Ownership of a PAL is considerably lower than a dedicated Liquid and Headspace Sampler.

Combi PAL Autosampler
The CombiPAL is an autosampler, headspace analysis and liquid injections possible. In addition to these basic functions, but many more applications are possible. Can be optionally automated solid phase micro extraction (SPME) is carried out. With the Cycle Composer control program, the user is able to reprogram the CombiPAL is completely free and to automate a variety of sample preparation steps. In combination with the Optic 3 multi-injection system and the option LINEX can change the sampler with highly complex samples automatically GC liner. A wide range of additional equipment options rounds out the offerings.
The main feature of CombiPAL is its flexibility. He may not just one but all the existing injectors. The "conversion" of headspace to liquid injection is just a simple syringe exchange. The control of the CombiPAL either via a control panel or via the control software Cycle Composer.
Head Space The function of the headspace CombiPAL consists of an oven for 2-20ml Headspace vials and a heated syringe, which is flushed after each injection with an inert gas. The furnace has a horizontal shaking ("agitator") in order to achieve rapid equilibration. The Headspace vials may be using a magnet in the injector from the rack in the headspace oven and back.
Solid-phase microextraction SPME Optionally, the CombiPAL the solid phase microextraction or SPME (Solid Phase Micro Extraction), automatically. The SPME option consists essentially of a holder that operates a syringe instead of the SPME fiber. A SPME fiber consists of fused silica and coated with a stationary phase. This fiber can accumulate analytes from a liquid sample or the supernatant steam room. After equilibration, the fiber is desorbed directly in the GC injector. The SPME covers a similar range as the headspace analysis, but may be more sensitive due to the enrichment. SPME is the simplest and most elegant way to automate sample preparation with solid phase enrichment. The very important in SPME reproducible equilibrium can be achieved with the Combi PAL in several ways: by equilibration in the test tube directly, through agitation in the headspace oven or with an additional magnetic stirrer.
Application systems with the CombiPAL The CombiPAL is due to its flexibility basis for many automation solutions Axel Semrau GmbH & Co KG. Some examples are the H53 automation, on-line SPE-coupling, derivatization or automatic liner exchange in the Optic 3 injector
