Certified UV/Vis Reference Materials for Spectrophotometers

Regular testing of spectrophotometers with certified reference materials secures measuring results as well as the traceability of measuring results to international standards (e.g. NIST, European Pharmacopoeia). In order to calibrate spectrometers, the Hellma Analytics’ Calibration Laboratory, accre more

  • Experimental Workflow for Fast and Accurate Genotyping of Scrapie-resistant/sensitive Sheep

    Several scientific studies support the claim that natural scrapie is associated with polymorphisms at three codons within the sheep prion protein (PrP) gene. Genotyping of these codons (codon 136 [alanine, valine], 154 [arginine, histidine], and 171 [glutamine, arginine, histidine]) might enable breeding of sheep flocks with high resistance to scrapie. Fast and reliable high-throughput genotyping of sheep is a major issue, since scrapie is a serious problem in several European countries. To address this, an experimental procedure for DNA preparation and PCR-based detection of codon 136, 154, and 171 polymorphisms was established. more

  • Chemometric Spectroscopy

    Chemometric Spectroscopy is the term used to describe the direct combination of a spectroscopic measurement with a chemometric data evaluation procedure, typically a multivariate statistic method, so providing quick and reliable deduction of the qualitative and quantitative properties of a sample from its spectrum. A multi-linear regression (MLR) or partial least squares (PLS) regression is usually used for the quantitative determination of individual or combined parameters, while substance identification generally relies on techniques such as discriminant or cluster analysis. more

  • Beyond Quality Control

    Product quality in any arena can be traced back to variations in parts, materials, people, and processes. And since it has been observed that all work can be broken down into processes, all processes, manufacturing or administrative in nature, have inherent variability more
