Mobile GC/MS accepts samples as liquid, solid, or vapour

SAID to be the only mobile gas chromatograph mass spectrometer (GC/MS) that can analyse samples introduced in solid, liquid, or vapour phase, the Griffin 460 also provides continuous direct air monitoring and has multiple applications in field work. Available from…

Thermo Fisher’s latest invention: water

ULTRA High Pressure Liquid Chromatography (UHPLC) is a powerful separation technique involving high pressure (around 350bar, 5000psi or more) and small stationary phase particles of typically 2um or smaller. It also requires a solvent, of course. Thermo Fisher has introduced…

C8 column offers lower hydrophobic retention

THE NEWEST member of Thermo Fisher Scientific’s Accucore range of HPLC columns, the C8, has a shorter alkyl length bonded phase than the equivalent C18 phase. This gives lower hydrophobic retention and, says Thermo, enhances chromatographic performance without generating excessive…

Autosampler accessory streamlines IC workflows

BY AUTOMATING inline pre-injection measurements of conductivity and pH, the Dionex AS-AP Sample Conductivity and pH Accessory from Thermo Fisher Scientific will save users substantial time and effort, as well as providing more consistent results than manual methods, the company…

Syringe filters promise better sample prep

A REVAMPED range of single-use syringe filters from Thermo Fisher should make sample preparation in the laboratory more reliable process. Previously known as the Sun-Sri Titan2 and National Scientific Target ranges, the new Titan3 and Target2 filter ranges have been…

Seminars address EU Water Framework Directive

A SERIES of seminars being held in European cities in 2012 will focus on the EU Water Framework Directive and the recent changes it has made to regulations covering water analysis across the continent. These have important ramifications for laboratories…

Lab-on-a-truck makes US tour

YOU’VE heard of lab-on-a-chip, the incorporation of microfluidic circuitry into a sliver of silicon or plastic that promises to do to chemistry what transistors and integrated circuits did for electronics. At the other end of the scale we now have…

Chromatography vial made for lab automation

MADE of borosilicate glass in either clear or amber, the Ram Vial from JG Finneran is designed around the needs of laboratory automation systems. Its 12 x 32mm external dimensions are said to be optimum for robotic arm autosamplers to…
