C18 reveals the typical options with the alkyl group - non-polar and ionically inert in most frequent conditions. Retention from the C18 stationary stage emanates from weak van der Waals intermolecular pressure that attracts hydrophobic compounds. C18 along with other alkyl phases including C8 and C4 represent by far the most basic variety of rever… Read More

Generally, compounds with characteristic structures are typically hugely selective and delicate for detection. Absorbance detectors such as ultraviolet absorption detectors and photodiode array detectors are commonly used for HPLC analysis mainly because many goal compounds have chromophores due to double bonds inside their molecular structures. T… Read More

This doc discusses fluid flow and measurement. It starts by defining fluids and different types of fluid stream, including fluid statics handling fluids at rest and fluid dynamics managing fluids in motion. Important principles reviewed include things like stress differences in columns of liquid, Reynolds experiment demonstrating laminar and turbul… Read More
