The following is a set of examples for amounts of standard mix (at 200 and 2000
g/mL) to be injected into 20 mL of water to achieve the stated concentrations. See
Table 13-1, Example Calibration Concentration Table, on page 13-10
.
The formula used to calculate the amount needed for injection (as above) is as
follows (1 PPB = 1 ng/mL):
X = C
F
/ C
C
x 1000
L/mL x 1
g/1000 ng x 20 mL
[1]
where:
X =
L to be Injected
C
F
= Final Desired Concentration in ng/mL (PPB)

= Calibration Mix Concentration in

Uncap a new sample vial, tilt the vial, and transfer the sample from the sample
syringe, taking care to avoid aerating (bubbling) in the sample. Cap the sample
vial tightly. See
Figure 13-7
