  1. IR chemistry - instrumental anaylsis

    my last instrumental analysis lab was basically about becoming familiar with using an IR spectrometer. I used a salt solution with a sodium chloride salt plate although it was not stated in the procedure to do so. the IR spectra seems to have come out fine

  2. gc chemistry - retention time

    adjusted retention time is the time a species spends in the stationary phase. its the total time it takes the species to elute minus the time it takes for an unretained species to elute. corrected retention data accounts for the change in pressure from the

  3. gc chemistry

    What affects peak shape in gc? I know peak area is proportional to the amount of a species and tailing occurs due to adsorption of polar species. Also fronting can occur if too much sample is added but these are the only things i can think of that would

  1. gc chemistry

    i was asked if i would expect peak shapes to be the same for all standards on a non-polar column. the standards to be tested are pentane, hexane, heptane, octane, decane, cyclohexane, toluene, acetone, and 1- and 2-propanol

  2. IR chemistry - instrumental anaylsis

    Yea I know I was having a difficult time trying to figure out how to explain it. Basically I was using NaCl plates with the salt form of a drug although I wasn't supposed to. I was only supposed to use the free base form with the salt plates so I was
