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

Characterizing Plant Polysaccharides Using Size-Exclusion Chromatography
April 4th 2025With green chemistry becoming more standardized, Leena Pitkänen of Aalto University analyzed how useful size-exclusion chromatography (SEC) and asymmetric flow field-flow fractionation (AF4) could be in characterizing plant polysaccharides.
Investigating the Protective Effects of Frankincense Oil on Wound Healing with GC–MS
April 2nd 2025Frankincense essential oil is known for its anti-inflammatory, antioxidant, and therapeutic properties. A recent study investigated the protective effects of the oil in an excision wound model in rats, focusing on oxidative stress reduction, inflammatory cytokine modulation, and caspase-3 regulation; chemical composition of the oil was analyzed using gas chromatography–mass spectrometry (GC–MS).
