14 High Technology Gas Generators for Every Application


Leman Instruments has developed rapidly to become a leading European company specialising in the field of high technology gas generators. The specialist modules of scientific equipment concentrates on the provision of standard products, OEMs and in custom designed realisation involving high purity Hydrogen (H2 combined solutions for FIDs, GCs, purge air generations, CH4 and CO2


), Nitrogen (N2 scrubbers, N2 ), Zero Air and and multi gas for LCMS.


Individually equipped with high performance communication interfaces (RS485, Ethernet and WLAN options), the reliable instruments significantly reduce operational costs and provide a solid return on investment within the space of two years. Suitably slotting into laboratory, air quality monitoring and industrial environments, the apparatus has been strategically constructed to suit the majority of these related applications.


These premium quality modules also provide high pressure stability, essentially improving upon the resolution and detection limits of instruments, whilst the constant purity ensures there will be no contamination concerns. Integrating Proton Exchange Membrane (PEM), Pressure Swing Absorption (PSA) and Catalysis technologies, they can be easily controlled via a touch panel or iPad, proving incredibly easy to install and operate.

One of Leman Instruments’ newest innovations is its combined technology gas generator, the GC Station 60LC. The single unit incorporates an inboard compressor and is a concept unlike any other currently offered in the marketplace.


Another notable product from Leman Instruments is the range of Hydro 50ml/ min to 15 l/min High Purity Hydrogen Generators for FID and Carrier Gas to fit almost any type of application which needs High purity H2


production close to the consumer in laboratory environment.


Based on the field proven Solid Polymer Electrolyte (PEM) cell technology, pure Hydrogen is produced at low pressure from electricity and high quality distilled water (Zero Water). This process can be started on demand and does not require any caustic solution. The produced Hydrogen is available 24/7 with constant minimum purity superior to 99.995% and maximum at 99.99995% at output flows of 50ml/min to 15 l/min (depending on the model.) The H2


output pressure is regulated


electronically and can be set from 0.5 to 10 bar. (7 to 140 psig). More information online: ilmt.co/PL/dmOW

New Cannabidivarinic Acid Standard Advances Cannabis Analysis


Cannabidivarinic Acid (CBDVA) is a non-psychoactive cannabinoid reported to have anti-inflammatory properties. While its medicinal benefits are still being researched, quantifying this compound in cannabis samples is crucial for obtaining a true measurement of potency and chemovar identification. Restek now offers a new CBDVA certified reference material (CRM) to help labs advance their analysis of cannabis.


Restek’s new CBDVA standard is ideal for creating multipoint (5-point minimum suggested) calibration curves for LC analysis. With verified composition and stability, this prepared stock product eliminates the need for in-house standards preparation for greater convenience and lower labour requirements. As it’s excluded from US DEA Controlled Substances Act (CSA) regulatory controls, no customer permits or licensing required to purchase within the US and because it’s manufactured and QC tested in Restek’s ISO-accredited labs, this new CBDVA standard qualifies as a certified reference material (CRM) that satisfies your ISO requirements.

Wettable Phase for Analytical and Industrial HPLC


Kromasil C18(w) is a wettable HPLC phase specifically engineered for bio-separations as well as food and beverage analysis. The focus of this phase is for the analysis and purification of key biomolecules under aqueous conditions.


Kromasil C18(w) is part of the Kromasil Classic portfolio of perfectly spherical, totally porous silica media with 100 Å pore size. The phase is end-capped with different characteristics than the Classic Kromasil C18, as is shown in the comparing Tanaka diagram. This allows for separations and analysis of samples that are naturally provided in aqueous conditions. The wettable phase also enables new selectivity and resolution opportunities to isolate impurities and enrich samples containing compounds such as amino acids and peptides. The chromatography can be run under reversed phase (RP) conditions or in fully aqueous conditions, if required.


The Kromasil wettable phase is now supplied in both 5 and 10 µm particles. Columns are available from 4.6 to 21.2 mm ID. The larger particles are also available as bulk for packing in DAC systems - even repeatedly, as the well-known mechanical stability of Kromasil packing media also applies for this material.


Independently, if you work with analysis, development or screening, in pilot facilities or manufacturing, the flexibility and alternative selectivity offered by Kromasil


C18(w) can be of significant benefit for your facility in view of the wider spectrum of polar compounds that are currently investigated and purified in pharma and biotechnology companies. More information online: ilmt.co/PL/LpY9

All-in-One Analyser in a Wall-Mounted Enclosure for TVOC Monitoring and Emission Speciation Chromatotec Group®


specialises in the manufacturing of autoGCs for online monitoring. Besides its standard solutions for ambient application, Chromatotec®


The user expressed concern about the instrument footprint and the complexity of use. In contrast to laboratory GC-FID, the solution provided includes internal calibration and gas generators, eliminating the need for gas cylinders while offering a reliable and fully automated, standalone unit. It is housed in compact wall- mounted cabinets which can be compliant with CSA and IECEx certifications for safe and hazardous areas (ATEX).


In addition, the analyser can be coupled to an online sampling device for liquid matrices. Finally, a 4G router providing Internet connectivity is integrated, allowing remote diagnosis. A website hosted in the Cloud displays real-time results and history of concentration values and calculation of the dynamic mass flow for each parameter analysed. Its automatic reporting tool generates monthly reports for environmental, state legislators. Notification alarms sent by SMS, as well as emails, inform users of unacceptable concentration values or malfunctions.

is continuously developing new turnkey


solutions for gas analysis at industrial sites. Recently, autoGC-FID analysers in a complete wall-mounted enclosure were deployed in two channelled sources to monitor the point source emissions of a chemistry plant that manufactures pharmaceutical intermediates and APIs. Measurement of TVOCs as well as halogenated and oxygenated hydrocarbons used as solvents at ppm level is provided in 15 minutes.
