Saccharidic tracers in atmospheric aerosols

Ion chromatographic method that applies sensitive amperometric detection

01-05-2014

Atmosperic aerosols have a strong impact on the climate. Within the organic aerosol fraction, anhydrosugars and sugar alcohols are valuable tracers for biomass burning and biogenic sources. They are best determined by ion chromatography coupled to pulsed amperometric detection. Sample preparation ...

X-ray fluorescence analysis of unknown samples

TURBOQUANT - SPECTRO’s Answer to Screening Analysis

18-12-2013

TURBOQUANT, developed by SPECTRO Analytical Instruments, also uses the FP approach, but with the added refinement of using the incoherent (Compton) backscatter information from the sample for additional matrix correction. This renders detailed knowledge of the matrix composition unnecessary but ...

Cost efficiency in laboratories

Possible savings of up to €5,000 in energy costs over 10 years

01-08-2013

Cost and energy efficiency are rapidly becoming leading considerations when purchasing any piece of laboratory equipment. With key equipment and instrumentation operating continuously or for extended periods, it is perhaps not surprising that laboratories are capable of consuming more power than ...
