Crawford Scientific are offering what they describe as a “unique new method development service using HPLC columns at the cutting edge of current technology” to customers within the UK.
Tony Taylor, the company’s technical director comments “We have found, by talking to customers, that new technologies such as sub-2 µm particles, superficially porous silica and HILIC phases can cause technology or knowledge barriers within organizations to seeing what actual improvements and benefits can be realized by implementing these columns.
“We are, therefore, issuing a challenge to customers to submit their existing HPLC method and Crawford will visit the site with a translated method followed by a live demo using a 25% discount column from our current list. In this way there is minimum disruption or cost to the customer and everything to gain.”

Fundamentals of Benchtop GC–MS Data Analysis and Terminology
April 5th 2025In this installment, we will review the fundamental terminology and data analysis principles in benchtop GC–MS. We will compare the three modes of analysis—full scan, extracted ion chromatograms, and selected ion monitoring—and see how each is used for quantitative and quantitative analysis.
Characterizing Plant Polysaccharides Using Size-Exclusion Chromatography
April 4th 2025With green chemistry becoming more standardized, Leena Pitkänen of Aalto University analyzed how useful size-exclusion chromatography (SEC) and asymmetric flow field-flow fractionation (AF4) could be in characterizing plant polysaccharides.
