Detector Temparature: 300 cc <br /> Column Temperatures 400C hold for 3 minutes, <br /> looc/min ramp rate to 3000C or until at least 95% <br /> of all components are eluted. - - <br /> B.- AnalxHi_ (cant) <br /> 2. Chromatographic operations for detection of total <br /> - petroleum fuel hydrocarbons with BTX distinction, <br /> Detectors Photo- Ion_aation in series with Flame <br /> Ionization. _ <br /> Column: Carbopack B/3 percent sp-2500 <br /> Carrier Gas: Helium at 10xWmin. <br /> Infector Taaperature: 2000C <br /> Detector Temperature: 2500C <br /> Column Temperature: 1000C x 6 min to 2250C at <br /> 100C/min hold 25 min. or until at least 95% of all <br /> components are aluted. <br /> C. Ouantification <br /> Quantify Total - Petroleum Fuel Hydrocarbons by <br /> integrating all detectable peaks within the time <br /> period in vhich at least. 95% of the recoverable <br /> hydrocarbons are eluted. Calibration shall be <br /> based upon an appropriate fuel standard <br /> representative of the suspect fuel.' <br /> If an appropriate sample for calibration does <br /> not exist, as in the case of an aged fuel, <br /> calibration . shall be done using a "non-aged" <br /> rspresentative -fuel standard- <br /> Calibration . <br /> tandard_Calibration . should be established within the <br /> estimated range of contaminant. levels within the <br /> sample, based on odor or sheen or on -prescreaning <br /> measurements (1.e. , combustable gas meter, or I.R. <br /> method) . Where "ton-detactable concentrations" <br /> are reported, the level. of detection shall not <br /> exceed 10 ppm for soil nhd 50 ppb for water. <br /> PETROEMIM HI MOM4 M axXr.Ysis <br /> (High bailing point hydrocarbons) <br /> This analysis includes the range of diesel motor fuels <br /> and commerical grade jet fuels. _ <br /> -A. SA=21& Preparation <br /> 1. Water <br /> Use IPA method . 3510, Separation. (SpA manual <br /> 3W-846, Ap=i1 1964) . Acetone extraction with <br /> sample partitioning in haxans has been found to be <br /> RU acceptable preparation, however - other <br /> appropriate soivant'say also be used. <br /> 2-2 <br />
