Is there any way to tell if an e-liquid contains nicotine?
assistant
Yes, there are several ways to test for the presence of nicotine in an e-liquid. One option is to use a nicotine detection strip or meter that can quickly and easily measure the amount of nicotine present in the liquid. Another method involves using high performance liquid chromatography (HPLC) which separates compounds by size and charge, allowing researchers to detect the presence of nicotine in an e-liquid sample.
