Hello,
I am doing an analysis of formaldehyde content in a textile sample in accordance with the EN14184-1 method using UV/VIS spectrophotometer,
there are some questions wanna ask:
1. By EN14184-1 method, Formaldehyde is extracted from a textile sample with water at 40 °C. So why should the extraction temperature be kept constant at 40°C?
2. Is there any better instrumental method for this analysis? HPLC, GC?
thanks.
