Delivery of a cross-beam laser ablation system (cb-pld) with integrated energy-selective mass spectroscopy
A new mass spectroscopy
test by Ameritox became available in July; the test can identify three cathinone compounds and five other chemicals often found in bath salts.
Newman's team worked with two: UPLC-ESI-MS/MS (ultra-performance liquid chromatography-electrospray ionization-tandem mass spectroscopy
) and GC-MS (gas chromatography-mass spectroscopy).
Using chromatography and mass spectroscopy
, which can detect trace amounts of chemicals in a sample, scientists want to find out precisely what it is that these dogs smell, which might shed light on what cancer is and how best to attack it at the molecular level.

The blood samples were assessed from a concentration of 25-hydroxyvitamin [D.sub.3] using a sensitive liquid chromatography tandem mass spectroscopy
Among their topics are biomass supply logistics and infrastructure, the genetic transformation of switchgrass, pretreating biomass by aqueous ammonia for bioethanol production, lime pretreatment, the high-throughput screening of plant cell-wall composition using pyrolysis molecular beam mass spectroscopy
, cellulase assays, basic laboratory culture methods for anaerobic bacteria, the simultaneous saccharification and fermentation and partial saccharification and co-fermentation of lignocellulosic biomass for ethanol production, and small-scale production and quality requirements of biodiesel.
In the future, the use of mass spectroscopy
and liquid chromatography testing may help catch more of the athletes who are abusing anabolic agents.
This disjunction points us to more quantitative determinations of hemoglobin content including measurements of hemoglobin fragments, such as hemorphins, using mass spectroscopy
In the past, gas chromatography and mass spectroscopy
were used to read the chemicals with a high degree of accuracy.
A recent publication in a biotech journal acknowledges a Top 10 pharmaceutical company has utilized Digilab's sample preparation and fractionation technologies to expose standard and novel diabetes substrates in a Fourier Transform Mass Spectroscopy
experimental paradigm (Yates, et al., 2007).
