Prevent Small Leaks from Causing Big Problems with a Restek Leak Detector

New and improved, Restek’s electronic leak detector lets you pinpoint small gas leaks quickly and accurately before they cause bigger problems. Now, there’s no more waiting for a full charge—the unit can be operated during charging or used up to 12 hours between charges. This compact, handheld instrument detects a broad range of laboratory gases and indicates leak severity with both an LED display and audible tone. In addition, it comes with a flexible charging kit that includes both a universal AC power adaptor and a USB charging cable so you can charge anywhere, anytime. Using a Restek electronic leak detector to ensure all critical seals in the GC system are leak free is an easy way to prevent costly downtime, waste, and damage.

Quickly and Efficiently Extract Both Volatiles and Semivolatiles with New Triple-Phase SPME Fibers and Arrows

Restek first launched solid phase microextraction (SPME) automated sample preparation fibers to reduce sample handling and solvent consumption in many industries, such as environmental, food, and clinical. Soon after came rugged Restek PAL SPME Arrows, a revolution in microextraction that combines exceptional robustness with faster extraction times and trace-level sensitivity. Now, both fiber and Arrow lines are being expanded, including the addition of a sought-after triple-phase offering.

Of significant interest to many analysts, new triple-phase SPME fibers and Arrows provide exceptional versatility. This divinylbenzene (DVB)/carbon wide range (WR)/polydimethylsiloxane (PDMS) combination can be used for quick and efficient extraction of a wide range of both volatiles and semivolatiles, and it is an excellent choice for decision-making during method development because it combines the characteristics of three popular phases.

Analyze CO and CO2 at ppb Levels Easily and Accurately—Now on Your Thermo TRACE 1300/1310 GCs

Low-level detection of carbon monoxide (CO) and carbon dioxide (CO2) is critical for many applications. Restek’s methanizer (CH4izer) allows ppb-level determination of CO and CO2 using a cost-effective FID instead of more expensive instrumentation. Up until now, the methanizer was only available for Agilent GCs, but Restek has just released a version of the methanizer for Thermo TRACE 1300/1310 GCs that features the same benefits to your lab as the original model.

The methanizer is factory set to 380 °C to ensure efficient and complete conversion of CO and CO2 to CH4, but the operator can easily adjust the temperature as desired with the touch of a button. This unit controls temperatures precisely and reliably to within ± 1 °C of the defined set point and the actual temperature is shown in real time on an easy-to-read display. The Restek methanizer is less cumbersome than other models and is designed for easy installation and fast catalyst tube replacement, so you spend more time analyzing samples and less time on maintenance.

Whether you run an Agilent or a Thermo TRACE 1300/1310, the methanizer you need is now available at

Abstract:

Simultaneous measurement of 58 antipsychotic and antidepressant drugs in human urine can be achieved with a simple sample preparation procedure and a fast 5.5-minute LC-MS/MS analysis on a Raptor Biphenyl column. This method provides accurate, high-throughput determinations and is suitable for both clinical and forensic monitoring.

New Pesticide CRMs Released Specifically for Cannabis Labs in California and Similar States

Restek’s support for cannabis-testing labs continues to grow. This latest offering will help you meet the specific cannabis analysis needs of California set forth by the Bureau of Cannabis Control for regulated category I and II residual pesticide reporting—and of other states with similar regulations/programs. Ideal for creating multipoint (5-point minimum suggested) calibration curves for GC- and LC-MS/MS, these six mixes of prepared stock standards also eliminate the need for in-house standards preparation. And, as with all certified reference materials (CRMs) manufactured and QC tested in Restek’s ISO-accredited labs, they will satisfy your ISO requirements.
