General Information
Overview
EN ISO 23674:2022 - Cosmetics - Analytical methods - Direct determination of traces of mercury in cosmetics by thermal decomposition and atomic absorption spectrometry (mercury analyser) - specifies a laboratory procedure for quantifying total mercury (inorganic + organic) in finished cosmetic products. Adopted by CEN as EN ISO 23674:2022, the method enables direct solid analysis with no prior chemical digestion, using a thermal decomposition mercury analyser and atomic absorption detection.
Key topics and technical requirements
- Principle: Samples are thermally decomposed (combusted/ashed) in an oxygen flow; combustion gases pass through a hot catalyst, mercury vapour is trapped on a gold amalgamator and released by rapid heating. Detection is by atomic absorption at 253.7 nm.
- Temperature ranges: Typical combustion between 650 °C and 900 °C, catalyst around 615 °C, amalgamator release at 800–900 °C (as specified by the standard).
- Sample types: Valid for solid and liquid cosmetic samples; supports direct weighing of solids for analysis.
- Calibration: Covers both liquid and solid calibration standards and aims for a wide dynamic range using multiple measurement cell lengths when available.
- Quality control: Requires analysis blanks, quality control samples and replicates to monitor accuracy and precision. The standard discusses validation range vs validated range and method performance assessment (accuracy profile methodology is included in an informative annex).
- Reagents & materials: Minimal reagents (e.g., Grade 1 water per ISO 3696) are referenced; safety warnings and instrument/operational requirements are provided.
- Documentation: Specifies required elements for test reports and performance validation.
Applications and who uses it
- Cosmetic manufacturers for routine quality control and release testing to ensure products meet regulatory limits for mercury.
- Control laboratories and contract testing labs performing trace contaminant analysis in toiletries and personal care products.
- Regulatory agencies and market surveillance bodies verifying compliance with safety standards and consumer protection requirements.
- Product safety and R&D teams assessing ingredient sourcing and formulation changes for mercury contamination risk.
This method is especially valuable when rapid, digestion-free analysis is needed and where total mercury (any species) must be quantified directly in finished products.

validation range
range from the upper to the lower concentration of samples used for the method evaluation
3.2
validated range
range of concentrations between the upper and lower levels that the method performance has been
demonstrated to be compliant with the method requirements
Note 1 to entry: The validated range shall not be confused with the validation range (3.1); it can be smaller.
4 Principle
The described method uses integrated instruments allowing mercury traces quantification. Samples
are weighed with no need of any chemical sample preparation as they are thermally decomposed in the
instrument (burned or ashed) in an oxygen flow at high temperature (between 650 °C and 900 °C). The
combustion gases travel through a catalyst tube set at about 615 °C. This step ensures conversion of
interfering components to forms that do not interfere and that are subsequently flushed. The resulting
mercury vapour is enriched on a downstream gold amalgamator and is then released as atomic
vapour by rapid heating of the amalgamator at a temperature of 800 °C to 900 °C. The atomic vapour
ISO 23674:2022(E)
is passed through a measuring cuvette system. The quantification occurs thanks to absorption at
253,7 nm. A wide dynamic range may be achieved by simultaneously passing mercury vapours through
measurement cells of different lengths.

5.1 Water, conforming to Grade 1 of ISO 3696 (conductivity below 0,1 μS.cm at 25 °C).
5.2 Hydrochloric acid, minimum mass fraction w = 30 %, density = 1,15 g/ml, suitable for elemental
analysis.
5.3 Diluted hydrochloric acid, produced by mixing hydrochloric acid (5.2) with ultrapure water
(5.1) at a ratio of approximately 1+9 parts, respectively.
5.4 Diluted nitric acid, prepared by diluting nitric acid of minimum mass fraction w=60 %,
density = 1,15 g/ml, suitable for ICP-MS with pure water (5.1) at a ratio of 1+9 respectively.
[2]
If diluted nitric acid is chosen to dilute the analyte stock solutions, it is recommended to add
[3]
L-cysteine at 0,1 g/l .
5.5 Analyte standard stock solutions (mercury), 1 000 µg/ml (commercially available).
5.6 Analyte standard stock solutions (mercury), 10 µg/ml [commercially available or freshly
prepared by dilution in the same dilution medium as calibration solutions (5.3 or 5.4) of a more
concentrated solution for example at 1 000 µg/ml such as 5.5].
Analyte standard stock solutions 5.5 or 5.6 can be used for this document according to their availability
on the local market. Recommendations from the supplier of stock solutions regarding stability (expiry
date and storage conditions) shall be followed to avoid mercury loss.
6 Apparatus and equipment
All apparatus and equipment that come into direct contact with samples or solutions should be pre-
cleaned with diluted hydrochloric acid (5.3) and rinsed with ultrapure water (5.1) to ensure the lowest
analytical background. To prevent contamination and adsorption, do not use laboratory materials made
up of borosilicate glass. The use of diluted nitric acid (5.4) is also permitted. To check the efficiency of
the cleaning step, a blank measurement can be performed prior to the analytical sequence.
Elemental mercury analyser with instrument control unit and sample containers made of suitable
materials (e.g. nickel, quartz glass or ceramic) are used. The sample containers usually have a capacity
of approximately 500 mg of solid sample or 500 µl, 1 000 µl and 1 500 µl of liquids. Mercury analysers
are equipped with an element-specific lamp for mercury. The mercury line of 253,7 nm is used.
Many instruments from several brands are available on the market and often marketed as “mercury
analysers”. The list of instruments that have been used for the interlaboratory test validating this
document is given in Annex A.
ISO 23674:2022(E)
7 Calibration
7.1 General
The aim of this step is to build a calibration curve by introduction in the instrument of increasing
mercury amounts. This calibration curve allows to get instrument response as a function of mercury
amount (in ng). At least 5 calibration standards shall be used in a range including the expected amounts
of mercury in the samples. Calibration of the instrument remains stable and is not mandatory prior to
each series of analyses provided that quality control (QC) requirements are met (see 10.2).
Due to the specificity of the technique towards mercury element, measurement of traces of mercury
in samples is weakly affected by interferences and matrix effects. Since the technique is relatively
insensitive to the matrix type, calibration can be performed either using in-house liquid (see 7.2) or solid
(see 7.3) calibration standards. However, moisture and organic contents may affect quantification. Such
differences between calibration standard and cosmetic samples shall be neutralized. For differences
in moisture content, optimize the drying times. For differences in quantity of organic material to be
combusted, optimize the time and temperature of combustion. For differences in interfering element,
optimize time for the catalytic conversion of elements needing catalytic conversion into a chemical
form that does not interfere with mercury detection.
7.2 Liquid calibration standards
Calibration solutions should be prepared in either diluted hydrochloric acid (5.3) or diluted nitric acid
containing L-Cysteine (5.4) to ensure stability of mercury. For laboratory convenience, calibration
solutions may be prepared in other acid mixture solutions, provided the operator checks the stability
of the mercury in that solution. Fresh calibration solutions should be prepared each time calibration is
needed. Two solution calibration procedures are possible.
— Introduce increasing amounts of mercury in a constant volume using increasing concentrations of
standard solution (see Table 1).
— Introduce increasing amounts of mercury using increasing volumes of one or more standard
solutions with a given mercury concentration (see Table 2).
Below are examples for these two ways of performing calibration.
