A complete molecular-scale picture of how plants convert sunlight to chemical energy has been obtained at Purdue University in the US, offering potential new insights into animal metabolism as well.
Manufacturing processes of pharmaceutical tablets may change the morphology of the crystalline state of the active pharmaceutical ingredients (API) or the excipients
A University at Buffalo chemist has developed a new, high-throughput method for obtaining nuclear magnetic resonance data that can potentially performing orders of magnitude faster than conventional methods
Small, irregularly shaped samples can present difficulties for the established methods of metal analysis. Laser-ablation ICP-MS offers accuracy and precision independent of sample form
Alltech ELSD 800 is an evaporative light scattering detector that can add universal HPLC detection to any LC system to replace or complement existing detectors. The ELSD's universal response gives a closer representation of sample mass than UV detectors, making quantification more accurate when standards are not available. It can be used in parallel with MS to obtain maximum structural and concentration information for each sample. Unlike RI detectors, the ELSD offers high sensitivity, equilibrates quickly and is gradient compatible.
The Scentograph Plus II portable gas chromatograph features dual detectors, dual sequential column, internal carrier gas and calibration tanks and capillary injection port. Accessories including the dual sampling purge and trap or stack gas sampler allow the instrument to produce laboratory quality results at on-site locations.
The OxyBaby handheld MAP oxygen analyser can be used to check residual oxygen levels at regular intervals. OxyBaby is handy, doesn't require power leads and is simple to use. It is portable and suitable for making quality checks of packed foods such as meats, sausages, fish, dairy products, bakery products, pasta, pizza and salads. Oxygen levels can be determined at any time by simply picking a pack off the line and inserting the needle. OxyBaby is designed so that it can be held in one hand with the packaged food product in the other.
Using photosynthesis as their model, chemists at Washington University in St Louis, North Carolina State University, and the University of California, Riverside have tested molecular electronic switches that turn the flow of light energy on and off
The application of Raman spectroscopy in the field of pharmaceuticals is showing immense potential. Previous progress has been hindered due to the high cost and poor user-friendliness of the old Raman technology
BioTOF-Q is an ultra-high performance electrospray ionisation (ESI) mass-selective quadrupole/collision quadrupole/time-of-flight analyser (Q-q-TOF) mass spectrometer. It adds tandem mass spectrometry (MS/MS) capabilities to the Bruker BioTOF II high-resolution LC-ESI-TOF system.
Panametrics' CGA351 zirconium-oxide based oxygen analyser uses an advanced zirconium oxide sensor in combination with a new manifold assembly to ensure leak-free integrity and accurate measurement of oxygen content from percent levels to less than 0.1 ppm.
Laboratory scientists have for many years used infrared (Infrared Spectrometers Near, Mid and Far) to quantitatively and qualitatively analyse solid, liquid and gaseous samples
