| I have a calibration curve for methyl salicylate (MeS) from Gas Chromatography (GC). Calibration curve point taken into account are 1ppm , 10ppm, 100ppm vs. respective area from GC . I am trying to bubble MeS gas into impinger in known solution at known amount of quantity. From this solution I can get area from GC. Question is how I can calculate concentration of MeS bubbled in inpinger. Points to be noted: 1) MeS used for calibration is in liquid state 2) Concentration of MeS stream to be calculated is in vapor phase 3) Molecular weight of MeS 152.1494 g/mol 4) Same solution used as a solvent for preparing calibration curve and solvent in impinge Things I can’t Do: Considering weight of impinge before and after bubbling (too many removable parts ) Some Reference: 1ppm = 0.001gm/Lit = 1mg/L 10ppm = 0.01gm/Lit = 10mg/L 100ppm = 0.1gm/Lit = 100mg/L Below conversion useful if quantity is in gases state The conversion equation is based on 25 ºC and 1 atmosphere: X ppm = (Y mg/m3)(24.45)/(molecular weight) Pls Help !! Thank you in advance Last edited by sweet_chemical; 10-09-2009 at 09:47 PM. |
