18 May / June 2016 All in One Unit for GC Applications Announced


Leman Instruments is a leading European company, specialised in standard products, OEMs and in custom designed realisations involving high purity H2, N2, zero air, combined solutions for FIDs, GCs, purge air generators, CH4 & CO2 scrubbers, N2 and multigas for LCMS with high level of communications involving Ethernet, USB, RS 485 and possibility of AK protocol integration.


A recent Leman Instruments’ innovation is its combined technology gas generator, the GC Station 60LC. This single unit incorporates an inboard compressor and is a concept unlike any other currently offered in the marketplace. The system is unique to Leman’s brand and has delighted customers with its practicality. Combining high purity hydrogen, zero air and nitrogen generators, the product acts as a fully automated solution.


Further developments include new communication protocols which Leman have established for the benefit of customers to ensure they are provided with all necessary information. All of Leman products are part of this system; the technology and protocols can be easily integrated with systems all over the globe.


Leman Instruments also offers a range of hydro 50ml/min to 30 l/min and above with high purity hydrogen generators for FID and carrier gas. These fit almost any type of application which needs high purity H2 production close to the consumer in laboratory or industrial 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. The hydrogen produced is available 24/7 with constant minimum purity superior to 99.995% and maximum at 99.99999% at output flows of 50ml/min to 30 l/min in standards configuration. The H2 output pressure is regulated electronically and can be set from 0.5 to 10 bar. (7 to 140 psig).


Each instrument is equipped with high performance communication interfaces (RS485, Ethernet, WLAN) to create a very flexible gas network with local or central control. Due to the software being focused on safety, automatic regulation and reliable communications, Leman’s products are easy to install, reliable, safe and pleasant to operate.

HPLC Columns – Packed by the Sorbent Manufacturer


MACHEREY-NAGEL, manufacturer of


chromatography sorbents, developed the HPLC sorbent NUCLEOSIL®


more than 40


years ago. It was one of the first spherical type A silicas and is still manufactured by MACHEREY-NAGEL. It comes


in numerous modifications, particle and pore sizes. Manufacturer-packed HPLC columns are available with nonpolar RP phases (e.g., C18, C18 HD, C8, C6H5) and polar phases (e.g., CN, NH2, SA, SB, SiOH). They are often applied in validated methods.


For nearly 15 years, they have supplemented their successful NUCLEOSIL® range with the fully synthetical type B silica NUCLEODUR®


product – a state-of-the-art silica for


professional solutions. Several different surface modifications have been developed over the last years providing a full range of specified HPLC phases (e.g., C8 and C18 Gravity, C18 Isis, C18 Pyramid, PolarTec, Phenyl-Hexyl, Sphinx RP, PFP, HILIC). The recently launched NUCLEODUR®


C18 Gravity-SB features hydrophobic and polar selectivity for a


better retention of early eluting analytes. With the NUCLEOSHELL®


core-shell particle technology MACHEREY-NAGEL introduced


a superficially porous silica for highest efficiency in HPLC. Besides the C18 modifications RP 18 and RP 18plus, innovative chemistries such as Phenyl-Hexyl, PFP, and HILIC are available. NUCLEOSHELL® control.


columns fulfill the high demands in research and quality For further information visit: www.mn-net.com/HPLC
