Nicotine dose consistency testing

Description

ADACT offers nicotine dose consistency testing for e-liquid devices. This is a key requirement of the MHRA for TPD registration in the UK. E-liquid devices are required to deliver a uniform amount of nicotine throughout their use.

Our team of scientists are passionate about delivering accurate, reliable scientific results. We test e-liquid devices in our ISO/IEC 17025:2017 accredited laboratory in Yorkshire, England.

We can offer you a faster delivery of your results, turning results around in 5-10 working days.

How we test e-liquid devices

Our scientists will generate vapour from your Electronic Nicotine Delivery System (ENDS) device in accordance to the manufacturer’s instructions and in compliance with ISO 20768. Next, we collect vapour from a series of 10 puffs with a duration of five seconds and an interval of 30 seconds. We repeat this four times to measure consistency over 40 puffs.

At the next stage, we analyse your samples of vapour with our Gas Chromatograph-Mass Spectrometry (GCMS) instrument to determine the amount of nicotine present. We determine the concentration of the compound as mg/ml and report this as nanograms per puff.

And finally, you will receive a Certificate of Analysis (COA) to use in your product registration with the MHRA.
