An LC separation specifies that the mobile phase be 25% tetrahydrofuran (THF) in water. Unfortunately, the laboratory supply of THF is temporarily exhausted. Thus, the mobile phase is made with acetonitrile (CH3CN) instead. What is the ratio of CH3CN/H20 that has the same strength?

(i.e. polar, non-polar, etc.)
Which statement is true? Statement 1: Since tiny amounts of material are exposed on an open surface, the use of TLC is limited to relatively nonvolatile substances.Statement 2: To determine the identity of a specific compound in a mixture, the TLC behavior of the test sample and that of authentic standard compounds are compared on the same plate.
Thin‑layer chromatography (TLC) can be used as a preliminary identification method for many amphetamine‑type stimulants (ATS). Using a 0.25 mm thick silica gel stationary phase and a 98.5:1.5 methanol:concentrated ammonia mobile phase, a spot was observed to have traveled 3.52 cm when the solvent front traveled 8.81 cm. What is the retardation factor (?F)for the compound that composes this spot?
