Sorbent Pens. For Next Generation Headspace Analysis

Sorbent Pens For Next Generation Headspace Analysis

Headspace Sorbent Pens - The Ultimate Extraction Power Introducing Entech s exciting new Sorbent Pen technology. The most versatile extraction and sample preconcentration technology available for GC and GCMS. Sorbent Pens combine the features of SPME and classical ¼ adsorbent traps in a design with far more flexibility and enhanced performance. Sorbent Pens are extremely durable and are designed to perform both active and diffusive sampling. The Sorbent Pen is then desorbed directly onto the head of a GC column to eliminate losses associated with standard thermal desorption systems that must transport the desorbed sample through rotary valves, secondary traps, and a lengthy transfer line prior to delivery onto the GC column. The Sorbent Pen uses an entirely new approach for sample extraction. Direct insertion of the Sorbent Pen into the vial headspace followed by evacuation of the vial through the top of the Pen allows a new technique called "Vacuum Assisted Sorbent Extraction", or VASE, to recover a far wider range of compounds than ever before. With Sorbent Pens, both VOCs and SVOCs can be measured in wastewater, breath condensate, alcoholic beverages, and virtually all other matrices. VASE offers a tremendous advantage over other extraction techniques that perform extractions at atmospheric pressure where diffusion rates are suppressed. Sorbent Pens perform sample enrichment offline from a GCMS, allowing all samples to extract simultaneously and for longer periods of time. This approach results in high throughput while yielding a more complete and reproducible extraction for more sensitive and quantitative measurements. The low cost 5800 Sorbent Pen Desorption Unit (5800 SPDU) makes this exciting new technique both affordable and practical for virtually any laboratory s budget. Then move up to 90 sample automation with the 7800 Autosampler for the ultimate in laboratory productivity. Join the Sorbent Pen movement and take advantage of the next generation in GCMS sample preparation. Improvements over SPME and Dynamic Headspace Trapping Applications include: Cannabis - Pesticide Screening Highly reproducible. - Terpene Profiling Very low carryover. - Potency Testing Durable - hundreds of injections. - CBD, THC Operates at or near equilibrium to improve sensitivity and quantitative accuracy. Perform exhaustive vacuum extraction of VOCs through SVOCs. Unlike SPME, outer sheath minimizes exposure to aerosols formed during agitation. See taints, odors, additives, flavors & fragrances at levels below previously possible. Faster injection rates produces better chromatography / less thermal degradation. Rapid injections without cryogen or electronic cooling. Usually requires no secondary bakeout/cleanup. Higher sensitivity and throughput via off-line extraction. Sample up to days under vacuum for unsurpassed SVOC recovery. Sample at elevated or sub-ambient temperatures as needed.

VASE using Sorbent Pens Operates at or Near Equilibrium to Improve Sensitivity and Reproducibility Operating at or near equilibrium increases sensitivity and reduces run to run variability Small movements back and forth on curve for VASE as the samples approach equilibrium causes little change in recoveries, and therefore reproducibility.

Sorbent Pen Desorption Unit (SPDU) Sorbent Pens are analyzed using the 5800 SPDU. After sample enrichment, simply insert the Sorbent Pen into the 5800 SPDU, and press START on the 5800 SPDU Controller. The complete desorption process is performed automatically to transfer both volatile and semi-volatile compounds onto the GCMS for extremely sensitive and accurate headspace analysis. Control the desorption temperature to either limit or maximize the molecular weight range transferred onto the column. A unique desorber design utilizes a Silonite coated flow path, allowing simple liner replacement to maintain maximum inertness for optimum long-term performance. Methods are created and stored on the same PC operating the GCMS. Develop methods using this entry level solution and then add the 7800 Autosampler when you are ready to fully automate the analysis of up to 90 Sorbent Pens. 5800 SPDU Easily transfers volatile and semi-volatile compounds to a GCMS for extremely sensitive and accurate headspace analysis. 5800 SPDU Ordering Information DESCRIPTION PART # UNIT Sorbent Pen Desorption Unit (0VAC) 5800-SPDU EA Sorbent Pen Desorption Unit (30VAC) 5800-SPDU-HV EA 5800 SPDU Liner for Headspace Sorbent Pen 5800-LNR-HS EA GC Model Mounting Kits: Agilent 6890/7890(B) 5800-GC-AG EA Thermo 300/30 GC 5800-GC-TH EA Shimadzu 00 GC 5800-GC-SH EA 3

Sorbent Pen Autosampler The 7800 Autosampler automates the analysis of up to 90 Sorbent Pens using 3 removable 30 position trays. The ability to use Sorbent Pens to pre-extract the headspace in a sample vial, or perform air sampling in almost any location, followed by rapid delivery to a GCMS creates the ideal combination of sensitivity and efficiency. The 7800 delivers each Sorbent Pen to the 5800 SPDU for GCMS injection and bakeout. After bakeout, the 7800 returns the Sorbent Pen to the sealed sample tray leaving clean Pens that are usually ready for resampling without further conditioning. The Sorbent Pen's unique triple o-ring seal ensures leak tight connections, while the design of the 5800 provides rapid and reproducible transfer to the GC column to support quantitative headspace analysis. The combined power and simplicity of the Sorbent Pen and 7800 / 5800 SPDU provides an ideal solution for recovering a vastly extended range of compounds in the sample headspace, allowing development of hundreds of applications compatible with virtually any matrix. 7800 Sorbent Pen Autosampler Part# 7800-SPA Sorbent Pen Extraction System The Sorbent Pen Extraction System provides a convenient way to perform vial extractions using 30-position trays. Load the sample to be extracted into the vial, insert the Sorbent Pen, create a vacuum through the MicroQT seal at the top of the Pen, and then load the tray into the 5600 to start the vacuum extraction. The Sorbent Pen Extraction System agitates the samples at 30-300 RPM to speed up transfer of volatiles to the headspace, while heating the sample from ambient +4 C to 70 C. Extractions will be complete in 48 hours depending on the application.

Use the 380 for new Pens, Pens that were not isolated after desorption, and Pens that contained unusually high concentrations where complete removal of the residual sample did not occur during the previous analysis. Flow rate of thermal conditioning gas is controlled and monitored through a convenient front panel flow controller, while an internal valve starts and stops the flow of UHP Nitrogen at appropriate Sorbent Pen conditioning temperatures. 380 Sorbent Pen Thermal Conditioner DESCRIPTION PART # UNIT Sorbent Pen Thermal Conditioner (0VAC) 380-SPTC EA Sorbent Pen Thermal Conditioner (40VAC) 380-SPTC-HV EA 5
