Tobacco Products Directive and Eliquid Lab Testing Processes

The Tobacco Products Directive requires eliquids to be tested and approved by the Medicines and Healthcare products Regulatory Agency.  Depending on your requirements Eos Scientific eliquid testing labs analyses your eliquids as below.

Our expert-led process allows us to accurately detect the ingredients in eliquids and emissions in their vapour. We screen for any undesirable compounds, provide accurate quantities of detected target compounds, and offer toxicology monographs on substances of concern. We also accurately determine nicotine levels and provide nicotine dose consistency reports.

Our eliquid testing labs are state of the art, bringing our expertise to your business. We have been helping companies get their eliquids tested and passed and we can help your business as well.

Eliquid Analysis for the TPD

With MHRA Submission:

  • Eliquid Analysis (Ingredients, undesirables including Tobacco Specific Nitrosoamines (TSNAs), nicotine level)
  • Emissions Testing (Aldehydes, undesirable thermal degradation products, trace metals)
  • Nicotine Dose Consistency
  • Recipe Calculation

Without MHRA Submission:

  • Eliquid Analysis
  • Emissions Testing
  • Nicotine Dose Consistency

Eliquid Analysis for Quality Control

  • Product Quality Analysis
  • Raw Material label claim and purity Analysis

Our Process of Analysis

Stage 01

GC-MS – eliquid analysis

Testing for:

Undesirables as per MHRA published list

Tobacco-Specific Nitrosamines (TSNAs for tobacco related flavours)

Nicotine strength to ascertain label claim

On passing stage 1 a toxicology monograph is created for each compound identified. In the event of an eliquid being found non-compliant, a reformulation will be required at this stage.  We can give advice on reformulation if requested.

If Eos Scientific is submitting eliquid to the MHRA on your behalf, a recipe calculation will also be created at this stage.

Stage 02

Emissions Testing

Testing for:

aldehydes

HPLC analysis

heavy metals

ICP-MS analysis

undesirables

TD-GC-MS analysis

TSNAs

LC-MS-MS

Nicotine Dose Consistency (either using TD-GC-MS or nicotine assay of eliquids)

In the event of a non-compliant emission or non-consistent nicotine dose a reformulation is required at this stage and the reformulated eliquid is retested, starting from stage 1.

After passing stage 2 your eliquids are ready to be submitted to the MHRA.
