Division 6.1 Response factor of nitromethane, calculated with reference to the internal standard used

If ‘n’ represents nitromethane:

let:

k_n

its response factor,

m'_n

its mass (in grams) in the mixture,

S'_n

its peak area.

If ‘c’ represents the internal standard, chloroform or 2,4-dimathylheptane:

let:

m'_c

its mass (in grams) in the mixture,

S'_c

its peak area,

then:

$$K_n=\frac{{\mathrm{m\text{'}}}_n}{{\mathrm{m\text{'}}}_c}\times \frac{{\mathrm{S\text{'}}}_c}{{\mathrm{S\text{'}}}_n}$$

(k_n is a function o² the apparatus).
