Today, the number of distinct GC column stationary phases has grown

In general, today's scientists are looking for more environmentally-friendly features

Exploring the latest technologies

Mass spectrometry (MS) has not quite become a routine acquisition for every lab that might benefit from it. Nor are MS instruments yet capable of serving routine users and experimenters equally well. But the characteristics and performance of instrumentation serving high and low-end applications overlap more now than ever.

Scientists started using true vacuum pumps more than 350 years ago, and investigators used suction pumps for more than 400 years before that. Consequently, removing gas to create a vacuum is not new in science. Nonetheless, the way of removing that gas keeps changing.

Ultraviolet-visible (UV-Vis) spectrophotometry is arguably the most common as well as one of the oldest forms of absorption-based analysis. UV and visible regions of the electromagnetic spectrum are contiguous: UV wavelengths range from 10 to 4000 angstroms; they are visible from 4000 to 7000 angstroms.

Gene sequencing is all about data—3.2 gigabytes for a single human genome, with several times that for making raw sequences relevant to real-world problems. Mining the genome for medical intelligence multiplies the data “crunch” for gene sequencers and value-added services that annotate gene sequences for their relevance to protein and metabolite concentrations, and to both diseased and healthy states.

Now is a good time to purchase an analytical balance if you’re in the market. Thanks to software algorithms that translate electrical signals to weight and improved user interfaces, analytical balances are now much faster in terms of measuring than they used to be. They are also much more accurate because of the efficiency of the algorithmic evaluation that turns data points into weight data and higher data acquisition speed.
