Application: | 2,3-Dimethylpentane may be used as an analytical reference standard for the determination of 2,3-dimethylpentane in: • Ambient air samples by thermal desorption-gas chromatography (TD-GC) in conjunction with Deans-switch cutting technique. • Exhaled air samples by GC combined with mass spectrometry (MS) operating under the selected ion monitoring (SIM) detection mode. • Indoor and outdoor air samples by adsorption using sorbent tubes, followed by analysis using TD-GC-MS with electron impact (EI) ionization. • Commercial reagent samples by high resolution GC using graphene-zeolite imdidazole framework (ZIF8) as a stationary phase. |
Application: | Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support. |
