Improve sample processing reliability and analytical performance with the Model 4100 Water/Soil Sample Processor. This automated instrument is efficiently built to process up to 100 drinking water, wastewater, or soil samples.
Say goodbye to handling and processing samples for purge-and-trap analysis of volatile organic compounds (VOCs). The 4100 Sample Processor is designed to operate with (single or dual) Eclipse 4760 purge-and-trap sample concentrators.
Improve sample accuracy and save lab counter space with the Model 4551A Water Autosampler. Designed to work with our 4760 Eclipse Purge-and-Trap Autosampler, the 4551A automates VOC analysis for up to 51 clean or lightly particulated water samples.
The extremely compact 4551A Water Autosampler fits strategically under the 4760 Eclipse to save bench space. The instrument precisely transfers water samples from standard 40-mL volatile organic analysis (VOA) vials to the sparge vessel of the 4760 Eclipse for purging.
The 4760 Eclipse Purge-and-Trap Sample Concentrator uses a slim-line design and intuitive user interface to analyze volatile organic compounds (VOCs) quicker and more efficiently. Use to effectively monitor drinking water, wastewater, groundwater, storm water and more!
The Model 4760 combines our 30+ years of VOC experience in one highly-productive instrument. Users can expect faster cycle times, higher sample throughput, and exceptional reliability.
Improved routine analysis of samples with high levels of involatile compounds, particulates and other solid matrix material
Matrix residue from samples can contaminate a GC inlet liner afterwithin a few runs, leading to peak broadening and loss of analytes through adsorption in the liner. Under such conditions, the analyst is forced to perform frequent liner replacement, an operation which normally requires manual intervention. Running large series of samples will represent a serious challenge.
GERSTEL Cooled Injection System – internationally the most frequently used PTV-type universal inlet, with patented septumless sampling head. Gas chromatographic analysis is now more versatile, reproducible and has lower detection limits than ever before, thanks to temperature programmed sample injection using GERSTEL Cooled Injection System.
When analyzing samples with high levels of involatile or insoluble matrix residue, GC inlet liners can become contaminated a after just a few runs. Matrix build-up can lead to peak broadening and loss of analytes through adsorption in the liner. Under such conditions, in order to get correct analysis results, the analyst must regularly perform a liner exchange, an operation which normally requires several manual steps. Using eLEX this complex task becomes quite simple: An ALEX sampling head is mounted on top of the Cooled Injection System (CIS) inlet and whenever the liner has to be exchanged the pneumatic lock is released.
The GERSTEL On-Column Injection Kit quickly, and easily converts a CIS into an on-column inlet.
The GERSTEL PYRO enables highly flexible and efficient automated pyrolysis of solids and liquids at up to 1000C combined with determination in a GC/MS system of the thermal decomposition products. If required, thermal desorption and pyrolysis of the same sample can be performed in sequence, enabling the analyst to obtain cleanest possible pyrogram and the maximum amount of information in the shortest possible time. Some key areas in which the PYRO is used are production quality control; product development; and forensic science.
The Tube Conditioner (TC 2) enables simultaneous conditioning of up to 10 TDS tubes or up to 50 GERSTEL Twisters.
Clean and well-conditioned TD tubes and Twister are essential in order to fully take advantage of the high sensitivity of the thermal desorption technique and to achieve the best possible quality of analysis. The TC 2 operates independetly of the GC/MS system, eliminating the risk of system contamination during conditioning and keeping the GC/MS available for analytical tasks ensuring maximum productivity.
The LV-20 Standards Addition Module pairs with our Model 4551A Autosampler to improve accuracy and precision of GC-GC-MS analyses, while minimizing standard usage and decreasing laboratory costs of expensive standards.
Designed as an option for the 4551A Autosampler, the LV-20 Standards Addition Module injects programmed volumes (1, 2, 5, 10, or 20 µL) of internal standard, surrogate, or matrix spike standards to improve the accuracy and precision of GC-GC-MS analyses. The LV-20 is equipped with high-speed injection valves which inject user-programmed volumes of standard with no excess overfill volume that fixed-loop based systems require to operate. All LV-20 functions are programmed using the intuitive touchscreen and Windows® CE software on the Eclipse 4760 Purge-and-Trap Sample Concentrator.
The GERSTEL Pyrolysis Module (PM 1) is an accessory for the Thermal Desorption System (TDS). The PM 1 enables heating of samples beyond the normal thermal desorption temperature limit of 400C to a final temperature between 500 and 1000C. Applications include the determination of thermal decomposition prodcuts from – and thereby the structure of – samples like paint, polymers, adhesives, plastics and packaging materials.
Adding the TDS A Autosampler enables your Thermal Desorption System (TDS) to perform completely automated processing of up to 20 samples using one or more analysis methods.
The Thermal Desorber TD 3.5+ is a flexible automated solution for thermal desorption and thermal extraction. The TD 3.5+ fits on top of any modern GC without the need for additional bench space and it is perfectly suited for the analysis material and for thermal desorption of sorbent tubes used to sample whole air. The TD 3.5+ handles standard 3.5″ tubes, as prescribed in several standard methods, in addition to GERSTEL plus tubes, which hold up to 20% more sorbent for enhanced break-through volume, improved recovery as well as improved limits of detection.
The GERSTEL Thermal Desorption System (TDS) is a flexible multi-functional system for highly sensitive determination of volatile and semi-volatile organic compounds (VOCs and SVOCs) that have been trapped on adsorbent tubes or on GERSTEL Twisters.
The TDS is also frequently used for direct thermal extraction and determination of VOCs and SVOCs from solids without sample preparation. Application examples are natural products, flavor and fragance, emssions from materials that are used indoors in buildings or in automobiles, semiconductors, polymers and packaging.
The worlds most flexible Thermal Desoprtion Instrument
The Thermal Desorption Unit (TDU 2) is a flexible automated solution for thermal desorption and thermal extraction. The TDU 2 fits on top of any modern GC without the need for additional bench space and it is perfectly suited for the analysis of gaseous, liquid and solid samples.
The TE is a preparation system for bulk samples to be analyzed using the Thermal Desorption System TDS.
A solid or gel sample is placed into the TE tube and is heated to the desired temperature. Compounds of interest are transferred into the TDS desorbent tube with a carrier gas flow. The compounds are the determined using the Thermal Desorption System (TDS).
Automated spiking of standard tubes for thermal desorption (TDU/TDS)
Why cumbersome and complicated when it can be done in such as simple way: In combination with the GERSTEL MPS Robotic series, the GERSTEL Tube Spiking System (TSS) enables atuomated generation of standard tubes for Thermal Desorption analysis. Adsorbent tubes are spiked with a user defined volume of liquid standard and solvent purged with a defined flow of carrier gas as required for method calibration and validation according to international standard methods. Up to five tubes can be mounted and spiked in every TSS unit and multiple TSS unis can be mounted on the MPS for higher throughput.
The GERSTEL TSPS is designed for the preparation of solvent-free thermal desorption standards for use in air and industrial hygiene analysis.
TSPS provides an excellent alternative to commonly used ‘one-at-a-time’ classic methods. The TSPS is simple in design, speeds up routine laboratory procedures and can be easily used by staff with any level of technical training.
The TSPS can be equipped with up to six GERSTEL thermal desorption tubes that are easily attached using a specially designed connection system.
