Quantitative determination of compound content in accordance with DIN EN ISO 11890-2 (Paints and varnishes - Determination of VOC and SVOC contents)

Posted Date:2025/8/19

10.2 Quantitative determination of compound content

10.2.1 Quantification with respect to CSRF

Determine the weight fraction of all such compounds of the product using Formula (4):

where

f_i is the weight fraction of compound i in % of the product;

r_i is the CSRF for compound i (see 8.3.3);

A_i is the peak area of compound i;

A_is is the peak area of the internal standard;

m_is is the mass, in grams, of internal standard in the test sample (see 8.2.1);

m_s is the mass, in grams, of the test sample (see 8.2.1).

10.2.2 Quantification with respect to surrogate standard

Determine the weight fraction of all such compounds of the product using Formula (5):

where

f_i is the weight fraction of compound i in % of the product;

A_i is the peak area of compound i;

A_DEA is the peak area of the surrogate standard;

m_DEA is the mass, in grams, of surrogate standard in the test sample (see 8.2.1);

m_s is the mass, in grams, of the test sample (see 8.2.1).
