BAM M320i Gasoline Reference Fuel
> This certified reference material is a gasoline matrix with certified values for benzene, aromatics, and oxygenates, used to validate GC-FID methods in fuel quality testing laboratories. It meets the definition of a certified reference material under heading 38.22 because it is accompanied by a certificate indicating certified property values, methods, and uncertainty. It is not a separate chemically defined compound, so it is not excluded by Chapter Note 1(a).
3822.90.00BCR-186 Skimmed Milk Powder Reference Material
> BCR-186 is a skimmed milk powder certified reference material with assigned values for pesticide residues and heavy metals, intended for validating analytical methods in dairy testing. It is accompanied by a certificate with property values and uncertainty, meeting the definition in Chapter Note 2(A). It is not a medicament or a foodstuff, so it is not excluded by Chapter Note 1(b) or (e).
3822.90.00EPA Method 1631 Mercury Calibration Standard
> This mercury calibration standard is a solution-based certified reference material with known mercury concentrations at ppb levels, used for validating ultra-trace mercury analysis methods like EPA Method 1631. It is accompanied by a certificate with certified values and uncertainty, qualifying under Chapter Note 2(A). It is not a separate chemically defined element because it is a solution preparation, so it is not excluded by Chapter Note 1(a).
3822.90.00IRMM-1027 Potassium Dichromate Gravimetric Standard
> IRMM-1027 is a high-purity potassium dichromate certified reference material with a certified purity value traceable to the SI, used for UV-VIS spectrophotometry calibration. It is accompanied by a certificate with values and uncertainty, meeting the CRM definition in Chapter Note 2(A). Although it is a separate chemically defined compound, it is not excluded because Chapter Note 1(a) only exempts specific products, and CRMs are explicitly included in heading 38.22.
3822.90.00LGC QC5021 Dioxin Calibration Standard
> LGC QC5021 is a certified solution containing 17 PCDDs/PCDFs at pg/mL levels for HRGC/HRMS dioxin analysis, used in environmental monitoring. It is accompanied by a certificate with certified values and uncertainty, meeting the CRM definition in Chapter Note 2(A). It is not a separate chemically defined compound as it is a mixture, so it is not excluded by Chapter Note 1(a).
3822.90.00NIST SRM 1577c Bovine Liver Standard
> NIST SRM 1577c is a powdered bovine liver certified reference material with certified concentrations of trace elements like arsenic, cadmium, and mercury, used for validating analytical methods in biological testing. It is accompanied by a certificate with values and uncertainty, meeting the CRM definition in Chapter Note 2(A). It is not a foodstuff or medicament, so it is not excluded by Chapter Note 1(b) or (e).
3822.90.00NIST SRM 3186 Glycerin (99.5% + Purity)
> NIST SRM 3186 is ultra-high purity glycerin certified for quantitative NMR and Karl Fischer water content analysis, used as a reference for pharmaceutical and food grade glycerol purity verification. It is accompanied by a certificate with certified values and uncertainty, meeting the CRM definition in Chapter Note 2(A). Although it is a separate chemically defined compound, it is not excluded because CRMs are explicitly included in heading 38.22.
