2,4,6-trichloroanisole - an overview | ScienceDirect Topics
After dissolution, a 100 μm PDMS SPME fiber is exposed in the vial headspace of the sample for 20 min at 30 C. The salt addition has to be fast enough to minimize any loss of volatile compounds. After headspace extraction, the SPME fiber was exposed in the GC injection port at 250 °C for 3 min, in splitless mode (3 min valve closed) and column temperature set at 40 °C.

Spectrophotometry - Wikipedia
A brief explanation of the procedure of spectrophotometry includes comparing the absorbency of a blank sample that does not contain a colored compound to a sample that contains a colored compound. This coloring can be accomplished by either a dye such as Coomasie Brilliant Blue G-250 dye measured at 595 nm or by an enzymatic reaction as seen between β-galactosidase and ONPG (turns sample yellow)
