AccuStandard®

EPA Method 500 SeriesMethod 502.2 Internal and Surrogate StandardsWith more proposed and promulgated methods available, analytical chemists are trying to combine analyte lists and shorten run-time while stilldemonstrating method equivalence. AccuStandard has formulated a core evaluation deuterated solution, and a second conventionalinternal/surrogate evaluation solution. Use of these formulations allows the analyst to quickly evaluate new ISTD/SS combinations for PID, Hall, FIDor GC/MS applications.Popular Internal StandardsM-502-IS$ 20 / 1 x 1 mL2.0 mg/mL each in MeOH 2 comps.1-Chloro-2-bromopropaneFluorobenzeneM-524-IS-22.0 mg/mL in MeOHFluorobenzeneM-524-IS$ 20 / 1 x 1 mL2.0 mg/mL each in MeOH 2 comps.1,2-Dichlorobenzene-d 4Fluorobenzene$ 12 / 1 x 1 mLM-502-IS-2$ 30 / 1 x 1 mL2.0 mg/mL each in MeOH 3 comps.1-Chloro-2-bromopropaneFluorobenzeneMethylene chloride-d 2M-001R$ 15 / 1 x 1 mL20 mg/mL each in MeOH 3 comps.Bromochloromethane1,4-Dichlorobutane2-Bromo-1-chloropropaneM-8020-IS$ 25 / 1 x 1 mL0.2 mg/mL each in MeOH 2 comps.4-Bromofluorobenzeneα,α,α-TrifluorotolueneM-8240/60-IS$ 30 / 1 x 1 mL0.2 mg/mL each in MeOH 5 comps.BromochloromethaneChlorobenzene-d 51,4-Dichlorobenzene-d 41,4-DifluorobenzenePentafluorobenzeneM-8260-IS-R$ 30 / 1 x 1 mL0.2 mg/mL each in MeOH 4 comps.2-Bromo-1-chloropropane1,4-Difluorobenzene1,4-Dichlorobenzene-d 4PentafluorobenzeneConventional ISTD/SSEvaluation MIxtureM-CONV-IS/SS$ 60 / 1 x 1 mL200 µg/mL each in MeOH 15 comps.2-Bromochlorobenzene4-BromochlorobenzeneBromochloromethanep-Bromofluorobenzene2-Bromo-1-chloropropane1-Chloro-2-fluorobenzene1-Chloro-3-fluorobenzene1-Chloro-4-fluorobenzeneM-502-IS-ASL$ 20 / 1 x 1 mL2.0 mg/mL each in MeOH 2 comps.2-Bromo-1-chloropropane1-Chloro-2-fluorobenzeneM-524-SS$ 20 / 1 x 1 mL2.0 mg/mL each in MeOH 2 comps.4-Bromofluorobenzene1,2-Dichlorobenzene-d 4M-624-SS-M$ 25 / 1 x 1 mL20 mg/mL each in MeOH 3 comps.4-BromofluorobenzeneFluorobenzenePentafluorobenzeneM-8020-SS$ 30 / 1 x 1 mL2.0 mg/mL each in MeOH 3 comps.4-Bromochlorobenzene1,4-DifluorobenzeneFluorobenzeneM-8021-SS$ 20 / 1 x 1 mL2.0 mg/mL each in MeOH 2 comps.4-Bromochlorobenzene1,4-DichlorobutaneM-8021-SS-M$ 20 / 1 x 1 mL2.0 mg/mL each in MeOH 2 comps.Bromochloromethane1,4-Dichlorobutane2-ChloropropaneDibromofluoromethane1,4-Dichlorobutane1,4-DifluorobenzeneFluorobenzenePentafluorobenzeneα,α,α-TrifluorotoluenePopular Surrogate StandardsISTD/SS Evaluation MixturesDeuterated ISTD/SSEvaluation MixtureM-DEUT-IS/SS$ 60 / 1 x 1 mL200 µg/mL each in MeOH 8 comps.Benzene-d 6Chlorobenzene-d 51,2-Dichlorobenzene-d 41,4-Dichlorobenzene-d 41,2-Dichloroethane-d 4Ethylbenzene-d 10Methylene chloride-d 2Toluene-d 8Popular ISTD/SS StandardsM-502-IS/SS$ 20 / 1 x 1 mL2.0 mg/mL each in MeOH 4 comps.1-Chloro-3-fluorobenzene2-ChloropropaneFluorobenzeneα,α,α-TrifluorotolueneM-502-IS-QC$ 20 / 1 x 1 mL1.0 mg/mL each in MeOH 3 comps.1-Chloro-2-bromopropane1-Chloro-2-fluorobenzeneFluorobenzeneM-524-FS$ 25 / 1 x 1 mL2.0 mg/mL each in MeOH 3 comps.4-Bromofluorobenzene1,2-Dichlorobenzene-d 4FluorobenzeneM-8010-IS/SS$ 25 / 1 x 1 mL150 µg/mL each in MeOH 3 comps.4-BromochlorobenzeneBromochloromethane4-BromofluorobenzeneM-8020-IS/SS-ASL$ 35 / 1 x 1 mL1.5 mg/mL each in MeOH 5 comps.4-Bromochlorobenzenep-Bromofluorobenzene1,4-DifluorobenzeneFluorobenzeneα,α,α-TrifluorotolueneMethod 502M-8260-IS$ 30 / 1 x 1 mL0.2 mg/mL each in MeOH 4 comps.Chlorobenzene-d 51,4-Difluorobenzene1,4-Dichlorobenzene-d 4PentafluorobenzeneM-8260A/B-IS$ 20 / 1 x 1 mL0.2 mg/mL each in MeOH 3 comps.Chlorobenzene-d 51,4-Dichlorobenzene-d 4FluorobenzeneM-8021A-SS$ 20 / 1 x 1 mLM-8240/60-IS/SS$ 45 / 1 x 1 mL20 mg/mL each in MeOH 4 comps.0.2 mg/mL each in MeOH 9 comps.4-Bromochlorobenzene 1,4-DichlorobutaneBromochloromethane 1,2-Dichloroethane-d 4Bromochloromethane 2-Bromo-1-chloropropanep-Bromofluorobenzene 1,4-DifluorobenzeneChlorobenzene-d 5 PentafluorobenzeneDibromofluoromethane Toluene-d 8M-8240/60-SS$ 30 / 1 x 1 mL1,4-Dichlorobenzene-d0.2 mg/mL each in MeOH 4 comps.4p-Bromofluorobenzene 1,2-Dichloroethane-d 4M-8260A/B-IS/SS$ 40 / 1 x 1 mLDibromofluoromethane Toluene-d 8200 µg/mL each in MeOH 7 comps.p-BromofluorobenzeneChlorobenzene-d 5Dibromofluoromethane1,4-Dichlorobenzene-d 41,2-Dichloroethane-d 4FluorobenzeneToluene-d 8Tel. 800-442-5290 / 203-786-5290 • Fax 203-786-5287 • Web AccuStandard.com 161
