1、Designation: D5197 091Standard Test Method forDetermination of Formaldehyde and Other CarbonylCompounds in Air (Active Sampler Methodology)1This standard is issued under the fixed designation D5197; the number immediately following the designation indicates the year oforiginal adoption or, in the ca
2、se of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1NOTEAdded research report information to Section 13 editorially in September 2010.1. Scope1.1 This te
3、st method covers a procedure for the determina-tion of formaldehyde (HCHO) and other carbonyl compounds(aldehydes and ketones) in air. Other carbonyl compounds thathave been validated for determination by this method includeacetaldehyde, acetone, propanal (propionaldehyde), methac-rolein, 2-butanone
4、 (methyl ethyl ketone), butyraldehyde, ben-zaldehyde, isovaleraldehyde, valeraldehyde, o-tolualdehyde,m-tolualdehyde, p-tolualdehyde, hexanal, and 2,5-dimethylbenzaldehyde. Acrolein and crotonaldehyde can notbe determined quantitatively using the analytical proceduredescribed in 10.2 due to the form
5、ation of multiple derivativepeaks and the instability of the peak ratios2, 3. However, theprocedure described in theAnnexAhas been used by the U. S.Environmental Protection Agency to estimate acrolein andcrotonaldehyde concentrations in standard atmospheres fol-lowing special precautions.1.2 This te
6、st method involves drawing air through a car-tridge containing silica gel coated with 2,4-dinitrophenylhydrazine (DNPH) reagent. Carbonyl compoundsreadily form stable derivatives with the DNPH reagent. TheDNPH derivatives are analyzed for parent aldehydes andketones utilizing high performance liquid
7、 chromatography(HPLC). The sampling procedure is a modification of U.S.EPA Method TO-11A (see 2.2).1.3 This test method is based on the specific reaction ofcarbonyl compounds with DNPH in the presence of an acid toform stable derivatives according to the reaction shown in Fig.1, (where: both R and R
8、1are alkyl or aromatic groups(ketones), or both, or either R or R1is a hydrogen atom(aldehydes). The determination of formaldehyde and othercarbonyl compounds, as DNPH derivatives, is similar to that ofU.S. EPA Method TO-11A in that it utilizes HPLC with UVdetection as the analytical finish. The det
9、ection limits havebeen extended to other carbonyl compounds that can bedetermined as outlined in Section 10.2.4. This test method issuitable for determination of formaldehyde and other carbonylcompounds in the concentration range from approximately 10ppb to 1 ppm (v/v).1.4 The sampling method gives
10、a time-weighted average(TWA) sample. It can be used for long-term (1 to 24 h) orshort-term (5 to 60 min) sampling of air for formaldehyde.1.5 This test method instructs the user on how to preparesampling cartridges from commercially available chromato-graphic grade silica gel cartridges4by the appli
11、cation ofacidified DNPH to each cartridge.1.6 The sampling flow rate, as described in this test method,has been validated for sampling rates up to 1.5 L/min. Thisflow rate limitation is principally due to the high pressure drop(8 kPa at 1.0 L/min) across the user prepared silica gelcartridges which
12、have a particle size of 55 to 105 m. Thesecartridges are not generally compatible with battery-poweredpumps used in personal sampling equipment (for example,those used by industrial hygienists.1.7 Alternatively, pre-coated DNPH silica gel cartridges arealso commercially available and may be substitu
13、ted providedthey can be demonstrated to perform equivalently.5Some ofthese use silica gel of a larger particle size that results in alower pressure drop across the cartridge. These low pressuredrop cartridges may be more suitable for sampling air usingbattery-powered personal sampling pumps.1.8 The
