Fast and easy GC pressure and flow calculations... anywhere, anytime
Agilent Profile
Agilent has created the first-of-its-kind gas chromatography app for the iPhone and iPod touch. The GC pressure and flow calculator app can be used to instantly and accurately determine pressures and flows through open tubular capillary columns. The app is based on the popular PC version that has been downloaded more than 10,000 times from the Agilent website. The GC calculator is a fast and easy way to:
See how different GC conditions affect column flow and pressure before setting up a system
Determine if your current column dimensions are appropriate and/or what your inlet pressure should be when switching from GC (atmospheric pressure) to GC/MS (vacuum)
Calculate new parameters when switching to a different carrier gas, such as going from helium to hydrogen for faster chromatography

SPME GC-MS–Based Metabolomics to Determine Metabolite Profiles of Coffee
November 14th 2024Using a solid phase microextraction gas chromatography-mass spectrometry (SPME GC-MS)-based metabolomics approach, a recent study by the School of Life Sciences and Technology at Institut Teknologi Bandung (Indonesia) investigated the impact of environmental factors (including temperature, rainfall, and altitude) on volatile metabolite profiles of Robusta green coffee beans from West Java.
RP-HPLC Analysis of Polyphenols and Antioxidants in Dark Chocolate
November 13th 2024A recent study set out to assess the significance of geographical and varietal factors in the content of alkaloids, phenolic compounds, and the antioxidant capacity of chocolate samples. Filtered extracts were analyzed by reversed-phase high-performance liquid chromatography (RP-HPLC) with ultraviolet (UV) and spectrophotometric methods to determine individual phenolics and overall indexes of antioxidant and flavonoid content.
AI and GenAI Applications to Help Optimize Purification and Yield of Antibodies From Plasma
October 31st 2024Deriving antibodies from plasma products involves several steps, typically starting from the collection of plasma and ending with the purification of the desired antibodies. These are: plasma collection; plasma pooling; fractionation; antibody purification; concentration and formulation; quality control; and packaging and storage. This process results in a purified antibody product that can be used for therapeutic purposes, diagnostic tests, or research. Each step is critical to ensure the safety, efficacy, and quality of the final product. Applications of AI/GenAI in many of these steps can significantly help in the optimization of purification and yield of the desired antibodies. Some specific use-cases are: selecting and optimizing plasma units for optimized plasma pooling; GenAI solution for enterprise search on internal knowledge portal; analysing and optimizing production batch profitability, inventory, yields; monitoring production batch key performance indicators for outlier identification; monitoring production equipment to predict maintenance events; and reducing quality control laboratory testing turnaround time.
