New DiatoSorb-W Diatomaceous Earth Provides Consistent Quality and Performance


DiatoSorb-W diatomaceous earth is a new alternative for analysts who depend on diatomaceous earth columns and struggle to find consistent product quality and reliable availability. Restek has developed DiatoSorb-W as a high-performing replacement for the diatomaceous earth that was previously used in their standard and Silcoport W GC packed columns lines.


DiatoSorb-W solid support is available in acid-washed (WAW), non-acid washed (WNAW), and high-performance (WHP) varieties, and all DiatoSorb-W solid support undergoes rigorous quality testing to ensure high purity and dependable performance. Virtually unlimited in supply, but only available from Restek, new DiatoSorb-W offers a reliable alternative for packed column users. Whether you need packed columns or loose packing materials, DiatoSorb-W products from Restek are always available and consistent in quality.

Headspace Autosampler Range Expanded to Support High-Temperature Applications


HTA is proud to announce the extension of its headspace autosampler solutions: after HT2000H and HT2100H, the HT2000HT is being introduced. The HT2000HT features an upper sample heating temperature of 300°C: it enables the execution of high-temperature headspace applications in a syringe-based system, without the constraints and limitations induced by valve&loop systems.


The HT2000HT incubation oven offers a 3-position heating and shaking chamber, allowing the simultaneous incubation of multiple samples.


The incubation temperature can be set between 40° and 300°C to accommodate the widest range of applications: the system can handle standard headspace applications (that require temperatures lower than 150°C), whilst still being well-suited to special high-temperature applications that include analysis of high-boiling compounds and polymers.


The HT2000HT features all the outstanding characteristics of HT2000H: compactness (near to zero requirement for bench space); universal compatibility (it can be interfaced with almost any gas chromatograph and it can serve both the front and rear injector in most supported GCs); ease to use by means of the full-colour touch screen interface; the lowest cost of ownership (no need for carrier gas); innovative technologies as vial leakage check and system integrity test.


The key feature that distinguishes HT2000HT within HTA headspace solutions is the support of temperatures up to 300°C, making it the ideal solution for polymer analysis, as well as quality control of chemical product materials and for heat-induced degradation studies.

LNI Swissgas is Proud to Announce its new MISTRAL ONE, Membrane Nitrogen and Air Generator for LC/MS applications.


The NitroGen series Mistral One are Membrane Nitrogen Generators. They are engineered to transform standard compressed air into a safe regulated supply of Nitrogen with purity up to 99.5%. As option 40 L/min of the compressed air is dried, pressure regulated and available to aliment most of the LC/MS analyzers. The Exclusive electronic flow control allows to generate Nitrogen with higher purity using a smaller volume of air and reducing energy costs and maintenance of external compressor. Continuous control of the operating parameters maintains the system at its maximum efficiency.


The Mistral One with its dual Nitrogen and Air outlets has been developed to meet specific requirements in terms of gas, flow, purity and pressure in LC-MS applications. It can be used for the evaporation of solvents in samples being analyzed.


Unique benefit and features:


• Compatible with all LCMS devices • Dual Nitrogen and Air generator • Exclusive electronic flow control • Generates Nitrogen on demand


• Low maintenance Designed to run 24 hours a day


• With low noise scroll compressor
