1 Scope
This European Standard stipulates a method for the analysis of pesticide residues in foods of plant
origin, such as fruits (including dried fruits), vegetables (including dried vegetables), cereals and many
processed products thereof by using GC, GC-MS(/MS), and/or LC-MS(/MS). The method has been
collaboratively studied on a large number of commodity/pesticide combinations. Precision data are
summarized in CEN/TR 17063. Guidelines for calibration are outlined in CEN/TS 17061.
2 Normative references

constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.
CEN/TS 17061:2017, Foodstuffs - Guidelines for the calibration and quantitative determination of
pesticide residues and organic contaminants using chromatographic methods
3 Principle
The homogeneous sample is extracted with the help of acetonitrile. Samples with low water content
(<80 %) require the addition of water before the initial extraction to get a total of approximately 10 g of
water. After addition of magnesium sulfate, sodium chloride and buffering citrate salts, the mixture is
shaken intensively and centrifuged for phase separation. An aliquot of the organic phase is cleaned-up
by dispersive solid phase extraction (D-SPE) employing bulk sorbents as well as magnesium sulfate for
the removal of residual water. Following clean-up with amino-sorbents (e.g. primary secondary amine
sorbent, PSA) and if necessary graphitized carbon black (GCB) or octadecylsilane (ODS), extracts are
acidified by adding a small amount of formic acid, to improve the storage stability of certain base-
sensitive pesticides. The final extract can be directly employed for GC- and LC-based analysis. Suitable
detectors for GC analysis are mass-selective detectors (MS or MS/MS) with unit or high mass resolution
or other GC detectors, such as flame photometric detector, FPD, and electron capture detector, ECD. For
the analysis with LC hyphenations with tandem mass-spectrometry (LC-MS/MS) or high resolution
mass-spectrometry are particularly suitable. Quantification may be performed using an internal
standard, which is added to the test portion before the first extraction, but this is not mandatory. Details
for calibration, see CEN/TS 17061.
4 Preparation and storage of the samples
4.1 General
Sample processing and storage procedures should be demonstrated to have no significant effect on the
residues present in the test sample (sometimes also called “analytical sample”). Processing should also
ensure that the test sample is homogeneous enough so that portion to portion (sub-sampling)
variability is acceptable. If a single analytical portion is unlikely to be representative of the test sample,
larger or replicate portions shall be analysed, to provide a better estimate of the true value. The degree
of comminution should support a quantitative residue extraction.
4.2 Laboratory sample
A laboratory sample that is wholly or extensively spoiled or degraded should not be analysed. When
possible, prepare laboratory samples immediately after arrival and in any event, before any significant
physical or chemical changes have taken place. If a laboratory sample cannot be prepared without
delay, it should be stored under appropriate conditions to keep it fresh and to avoid deterioration.
Dried or similarly processed samples should be analysed within their stated shelf life.

SIST EN 15662:2018
EN 15662:2018 (E)
4.3 Partly-prepared test sample
For preparation of the partly-prepared test sample take only the portion of the laboratory sample to
which the maximum residue level applies. No further plant-parts shall be removed.
The reduction of the laboratory sample shall be carried out in such a way that representative portions
are obtained (e.g. by sub-division into four and selection of opposite quarters). For samples of small
units (e.g. small fruits such as berries, legumes, cereals), the sample shall be thoroughly mixed before
weighing out the partly-prepared test sample. When the samples are made up of larger units, take
wedge-shaped sections (e.g. melons) or cross sections (e.g. cucumbers) that include the skin (outer
surface) from each unit [1].
4.4 Test sample
From each partly-prepared test sample, any parts that would cause difficulties with the homogenization
process should be removed. In the case of stone fruits, the stones shall be removed. This is the test
sample. A record of the plant-parts that have been removed shall be kept. Precautions should be taken
to avoid any losses of juice or flesh. Calculation of the residue shall be based on the mass of the original
test sample (including the stones where it is necessary).
Where the homogeneity of the test sample is not sufficient or the extraction of residues may be
significantly compromised due to large particle sizes, intensive comminution should be performed
using appropriate means. This is possible at ambient temperature, if separation of flesh and juice or
degradation of target pesticides does not occur to a significant extent. Comminution of samples in a
frozen state can significantly reduce losses of chemically labile pesticides and usually results in smaller
particle sizes and a higher degree of homogeneity. Cutting the samples coarsely (e.g. 3 cm x 3 cm) with a
knife and putting them into the freezer (e.g. −18 °C overnight) prior to comminution facilitates
processing. Processing can be also assisted and improved by cryogenic milling (using dry ice or liquid
nitrogen) by keeping the temperature below 0 °C. Especially in the case of fruits and vegetables,
cryogenic milling is much more effective at homogenizing commodities that have tough skins (e.g.
tomatoes or grapes) compared to milling at ambient temperature. Given the fact that non-systemic
pesticides often predominantly occur on the skin, cryogenic milling significantly reduces sub-sampling
variability. When processing test samples at low temperatures, condensation caused by high humidity
should be avoided. Residual carbon dioxide should be allowed to sufficiently dissipate so that its
contribution to weigh of the sample will be negligible.
4.5 Test portion
Individual test portions each sufficient for one analysis should be taken from the comminuted test
sample. These test portions should be analysed immediately. If test portions cannot be analysed
directly, the test sample or the test portions shall be frozen until required. If it is noted that
homogeneity of the test sample has been compromised during storage, the test sample shall be mixed
before taking test portions to ensure that homogeneity has been re-established.
5 Procedure
Extraction of samples is specified through modules E1 to E9. Extraction is usually followed by a clean-
up of the obtained raw extracts using the modules C1 to C5. Clean-up steps may be omitted if
interference of matrix load during analysis with chromatographic methods described in modules D1 to
D6 is not evident. In some cases clean-up could be replaced by dilution of the raw extracts (module C0).
Prior to the determination usually some stabilization of the extracts is performed (module S1). All
modules are described in detail in Annex A. Complementary information is given in Annex B.
