1、 WORLDWIDE ENGINEERING STANDARDS Test Procedure GMW15600 Determination of Aldehyde and Ketone Emissions in Vehicle Interior Cabin Air Copyright 2013 General Motors Company All Rights Reserved November 2013 Page 1 of 9 1 Scope Note: Nothing in this standard supercedes applicable laws and regulations.
2、 Note: In the event of conflict between the English and domestic language, the English language shall take precedence. 1.1 Purpose. This test procedure is used for the quantitative determination of aldehyde and ketone emissions in vehicle interior cabin air, utilizing a coated solid adsorbent follow
3、ed by High Performance Liquid Chromatography (HPLC) with ultraviolet (UV) detection. 1.2 Foreword. The determination of aldehydes and ketones in vehicle cabin air is essential to meet customer and regulatory requirements in global automotive markets. Concentrations are in the parts per million (ppm)
4、 ranges, which warrant accurate, analytical measurements. This test procedure is based on test method EPA T0-11A. It has been updated to reflect new technology in air sampling and analytical instrumentation. Note: There is no direct correlation between the limits on material, component, and vehicle
5、level due to the high complexity of chemical interactions, unpredictable influence of different part sizes and addition, interaction and elimination of their emissions. 1.3 Applicability. This test procedure can be used for all air samples for the determination of aldehyde and ketone emissions, incl
6、uding cabin air inside vehicles in a stationary or dynamic mode. The results will provide complementary information to interpret findings in GMW16818 and GMW15635 2 References Note: Only the latest approved standards are applicable unless otherwise specified. 2.1 External Standards/Specifications.

7、PA T0-11A ISO 12219-1 MOLIT 2013-549 HJ/T400 JASO Z125 2.2 GM Standards/Specifications. GMW15635 GMW16818 2.3 Additional References. 3 Resources 3.1 Facilities. The cabin air samples shall be collected inside a vehicle in a garage or in a stable environment with low background levels of aldehydes
8、. If data is acquired for regulatory purposes, the use of a vehicle sampling chamber may be required. The test chamber requirements and sampling protocol may differ for different regulations. 3.1.1 Calibration. The test facilities and equipment shall be in good working order and shall have a valid c
9、alibration label. 3.1.2 Alternatives. Alternative test facilities and equipment may also be used. However, all measuring variables as specified in this standard shall be determined correctly with respect to their physical definition.

This test procedure utilizes commonly available eq
11、uipment and instrumentation. Specific instrumentation and test conditions are noted in all the tables and figures in Appendix A through Appendix C. Other equipment can also be used when compatibility has been shown. 3.2.1 Test Apparatus. 3.2.1.1 High performance liquid chromatograph with (binary) pu
12、mp, solvent degasser, heated column compartment, auto sampler (optional), variable wavelength, or diode array detector, and computer based controller and data evaluation. System must be capable of gradient operation to 3.5 mL/minute and 350 bar (maximum), and ultraviolet (UV) detection at 360 Nm to
13、365 Nm. 3.2.1.2 HPLC column capable of separating the 2, 4-Dinitrophenylhydrazine (DNPH) derivatives of the specified aldehydes/ketones using gradient elution conditions. The column is critical for this procedure. 3.2.2 Sample Pump. Portable sampling pump with a minimum flow range between 50 mL/minu
14、te to 1000 mL/minute (e.g., Mine Safety Appliance Number 49772 or SKC AirCheck 2000). 3.2.3 Flow Calibrator. Appropriate flow calibrator (e.g., DC-1 flow calibrator, ) should be used to calibrate the sampling pumps prior to sampling. 3.2.4 Sample cartridges filled with 2, 4-DNPH on silica gel. Cartr
15、idges should have a capacity of 70 g of formaldehyde and blank values of formaldehyde 24 h is expected before analysis. 4.1.2 HPLC Determination of the Concentration of Aldehydes and Ketones. 4.1.2.1 Calibration Standards and Chromatograms. Calibration standard solutions of the aldehydes and ketones
16、 have to be prepared in concentrations of 0.1 g/mL to 15 g/mL (related to the corresponding carbonyl compound) in acetonitrile. 4.1.2.1.1 Calibration curves are created by measuring the calibration solutions by HPLC according to the test conditions in the tables and figures in Appendix A through App
17、endix C. For example: If using a Restek Ultra C18 column, use the HPLC instrument and solvent conditions in Appendix A, Table A1 and Table A2. See Appendix A, Figure A1 for chromatogram example. If using a Restek Allure AK 5 column, use the HPLC instrument and solvent conditions in Appendix B, Table
18、 B1 and Table B2. See example of chromatogram in Appendix B, Figure B1. If using a Phenomenex Synergi 4 m maximum column, use the HPLC instrument and solvent conditions in Appendix C, Table C1 and Table C2. See example of chromatogram in Appendix C, Figure C1. 4.1.2.1.2 Each measuring sequence shoul
19、d start with pure solvent. Afterward, calibration standards are measured with increasing carbonyl content (e.g., 0.1, 0.3, 0.5, 1.0, 3.0 and 15 g/mL). 4.1.2.1.3 Individual peaks in the samples are identified by their retention times and quantitated by evaluation of their peak areas. 4.2 Conditions.
20、4.2.1 Environmental Conditions. The environmental conditions are described in the respective sampling protocols that are used for testing. 4.2.2 Test Conditions. Deviations from the requirements of this standard shall have been agreed upon. Such requirements shall be specified on component drawings,
21、 test certificates, reports, etc. 4.2.3 Instrument. Set up the HPLC instrument with the conditions given in Appendices A, B, C, or equivalent. 4.2.4 Analysis. Each measurement should start with pure solvent followed by a standard solution. 4.2.4.1 Vials containing the derivatized carbonyl samples ca
22、n be placed after the standard, starting with the blank solution. Run the analysis sequence, injecting an aliquot from each vial using the HPLC conditions previously developed.
