May/June 2011 4th Generation of OPTIC™ Multimode Inlet for Gas Chromatography


After the worldwide success of three generations of OPTIC™ multimode inlet for gas chromatography (GC), ATAS GL International (Netherlands) has developed a new instrument, the OPTIC-4. Broadest range of capabilities of the previous generations is expanded with new features and solutions that cannot be found in any other GC inlet.


The patented low thermal mass design of the inlet body together with direct resistive heating provide fast linear temperature programming up to 600 °C at rates as high as 60 °C/s. In addition to standard sampling modes, the programmable inlet can operate effectively as Large Volume Injection, Pyrolysis or Thermal Desorption sample introduction device. With the options for sub- ambient cooling, backflush, cryogenic trapping


and automated liner exchange, OPTIC-4 is the world’s most versatile inlet for gas chromatography.


With the OPTIC-4, analyst can introduce into GC a wide range of samples including the ones containing high matrix or thermally labile compounds. The samples can also be water based or solid. Automated solvent venting procedure based on the standard solvent sensor in the split line makes large volume injections as easy as the industry standard split or splitless.


The new OPTIC™ inlet is designed to be installed on any GC make. The inlet and its control are also compatible with most of the autosamplers available on the market.

The Novel Triazole Bonded HILIC Column


Investment opportunity for innovative new


Chromatography product JPP Chromatography, a small UK technology company, announces the development of an air stable, single (one bottle) ‘hydrindantin-free’ ninhydrin reagent for amino acid analysis.


NACALAI TESQUE introduces COSMOSIL HILIC for hydrophilic interaction chromatography. This novel triazole bonded silica stationary phase provides higher polarity than non-modified silica columns, resulting in stronger hydrophilic interactions. The positively charged triazole stationary phase also offers an anion-exchange mechanism, enabling the strong retention of acidic compounds.


The COSMOSIL HILIC Chromatogram Index, which includes 167 chromatograms using COSMOSIL HILIC, is available on the NACALAI TESQUE website. This index is a useful tool for all chromatographers, assisting them to optimize analytical conditions for hydrophilic interaction chromatography.

All commercially available ninhydrin reagents sold for high performance ion chromatography amino acid determinations are currently based on the original 60 year old Moore and Stein method, which requires the presence of the highly sensitive hydrindantin as an ‘accelerator’. Two or more reagents must be mixed before use in the post-column reactor, where air must be rigidly excluded at all times - a tedious and inefficient process.


JPP’s reagent still causes a high speed reaction with amino acids and amines in the reaction coil at 130ºC to produce the intensely coloured Ruhemann’s purple. It can therefore be used on all ninhydrin based amino acid analysers without modification. It is totally unaffected by the presence of air, production is much cheaper, it is extremely stable and shelf- life is very long.


JPP’s over-riding aim was to come up with a product that makes life much easier for the end user, which it has succeeded in achieving. JPP seeks approaches from potential partners.
