  3. No mechanical or thermal stress
  4. High-grade steel capillary needle, which adds to its robustness
  5. Analyze a sample while extracting the next one
  6. Fully automatic use with a standard PAL system and any chromatographic system with split/splitless injector
  7. No extra thermal desorption system needed
  8. Total control of all extraction parameters
  9. More convenient than other extraction methods
  10. Less time necessary for sample incubation


**Phases available
PDMS, PDMS + 10% Carboxen, CT 5, CT 1701, CT 225, carbowax, PDMS/DVB,
PDMS/Carboxen/DVB, PDMS/Carboxen/Polyacrylate and 100% Polyacrylate on-hand as standard
phases.

 

SPME

chromsys049013.gif

CTC Analytics' Automated Solid Phase Micro Extraction (SPME) is a device designed to extract either specific organic groups or all types of organic compounds from a sample, depending on what type of fiber is used.

  9. PC cruise Control software
  10. Compatible with Agilent's ChemStation or ThermoFinnigan's Xcalibur software
  11. Use with 2mL, 10mL or 20mL vials
 

PrepBase

chromsys049006.jpgPAL PrepBase is an XYZ robot for "online filtration" automation, including sample preparation, transport and injection into an analyzer. It is designed to extract, heat, cool, shake or stir samples. It also can be used for diluting samples and preparing a dilution series. The PrepBase uses Whatman's Mini-Uniprep vials.

Key Benefits

  1. Suitable for all vial types
  2. Works with deepwell and microplates
  3. Dilution of sample and/or standards
  4. Prepares dilution series
  5. Extractions (SPE, SPME, SPDE)
  6. Filtration
  7. Sample shaking or stirring
  8. Sample heating or cooling
  9. Transports vials
 

PAL TDAS

chromsys049005.jpgThe PAL Thermal Desorption Autosampler (TDAS) was developed by CHROMTECH GmbH for fully automated thermal desorption. Organic compounds that vaporize or semi-vaporize can easily be analyzed in solid, liquid or gaseous samples with the PAL TDAS connected to a GC or GC/MS system.

Key Benefits

  1. Fully automatic thermal desorption sampler for large sample volumes
  2. Sample capacity of up to 293 samples
  3. "Moving Heater" technology
  4. Easy mounting on top of a GC injector
  5. Smart vial transport by PAL system
  6. Direct thermal extraction from sample vial to GC injector
  7. Heater oven temperature of up to 350° C
  8. No sample contamination
  9. No transfer lines or switching valves
  10. Adaptable to all PTV injectors
  11. Cruise Control software, PAL Cycle Composer
  12. Can be integrated with Agilent's ChemStation or ThermoFinnigan's Xcalibur


How Does It Work?

The system works as follows. First, desorption vials, crimped with regular caps, are transported from the sample tray to the heater inlet port by the PAL’s injection unit. As soon as the vial is placed into the heater, the injection unit pushes the vial and heater downwards, piercing both vial ends. The bottom of the heater, which is fitted with a syringe needle, injects the sample into the PTV when the heater is pushed down. The carrier gas flow then switches direction, passing through the desorption vial and onto the cooled PTV. All analytes are thereby refocused onto the cooled liner. After a 3 – 5 minute desorption at a high temperature, the PAL moves the thermal desorption unit out of the inlet. At that point, the flow is redirected back to the inlet, so that it no longer passes through the sample. After a short equilibration time, the PTV inlet heats rapidly to its maximum temperature. If you choose to do the heating while the PTV is in splitless mode, it will provide maximum sensitivity.

ITEX

chromsys049004.jpgIn-tube extraction and direct thermal desorption using proven industry standard adsorbents (Tenax TA, Carbotrap, Carbosieve etc.); syringe only concept for transparent sample handling, no sample loops, transfer lines, or switching valves; top mounted on GC's, saves valuable bench space; no GC injector modifications, no cryo-focusing necessary. Interfaces with any CombiPAL System, controlled by all major GC/GC-MS.



Mixing: Interval mixing 250rpm – 1500 rpm prior sample extraction

Steps of CombiPAL ITEX Cycle

  1. Sample is heated and / or agitated in a sealed sample vial until equilibrium is achieved
  2. The Trap needle pierces the vial septa and the syringe pumps the headspace through the Trap
  3. The loaded ITEX Trap is flash heated up to 350°C and desorbed into the hot GC Injector
  4. After thermal desorption the hot ITEX Trap is cleaned with inert flush gas

Vials and Supplies

Screw Top Vials

chromsys059010.jpg

The Only Approved Vials from CTC Analytics!

Since magnetic caps are fairly hard to crimp, La-Pha-Pack® has developed Screw-Top Vials (10ml + 20ml) and Magnetic Screw Seals for CTC PALs. The vials have a precision thread with several screw turns that force the septa against the vial, sealing it gas-tight. The center hole is designed to be suitable for SPME as well as for standard Headspace analysis, while providing enough surface for the magnet to transport a completely filled vial. The Screw-Top guarantees that the cap has a flat surface, so that the vial doesn't fall off the magnet. In the past, incorrectly crimped vials with deformed cap surfaces caused problems during transportation.

Post-analysis separation and disposal of the vial and seal are also possible in a more convenient way.

Key Benefits

  1. Reproducible results without the problems caused by incorrectly crimped vials
  2. Universally usable for Headspace and SPME
  3. Tested with regard to tightness, penetration and magnetic force during transportation of the instrument
  4. Out in the field, samples can be filled directly into the future analysis vial without the need for later sample transfer in the lab
  5. Much more convenient closure technique; no additional crimping tools necessary
  6. Easy separation of vial and seal post-analysis
