Determination of Diethyl Phthalate and Polyhexamethylene Guanidine in Surrogate Alcohol from Russia

Table 2

Comparison of method validation results for DEP.

Parameter	UV-VIS at 227 nma	^1H NMR
LOD (mg/L)	2.5	90
LOQ (mg/L)	10	181
Linear range (mg/L)	2-150	100–7000

aThe sensitivity is approximately a factor of 10 higher at 227 nm than at 276 nm.
