Function Dispense reference solution with internal standard into sample vessel

(FEED) on the 695 Autosampler.

Parameter Range; Default value / Meaning

Soln.name 8 characters; -

Name of the reference solution

The name of the reference solution must be identical to the name

entered on the "SUBSTANCES/Calibration" page under Soln.name (see

section 5.6.3). The mass concentration of the reference solution Mass

conc. must also be entered here.

The entry of a solution name is mandatory when the reference solution

should be added automatically. In this case the solution name

Soln.name must be entered in the parameter of the same name on the

"SOLUTIONS" page and assigned a position Pos. (see section 5.3.4).

Without entry of this name on the "SOLUTIONS" page or without a

position assignment, the reference solution must be dispensed manu-

ally (the prompt ADD "Soln.name" "V.add" > F then appears during

the program run).

V.add 0.010...50.000 mL; 0.100 mL

Solution volume that should be dispensed

Volume of the reference solution that should be dispensed into the

sample vessel.

Description The RADD>F instruction is used for the manual or automatic addition of a

reference solution to the sample vessel (FEED) on the 695 Autosampler.

This reference solution contains the reference substance needed for the

calibration technique with an internal standard (see section 6.9.6).

For automatic addition with the 695 Autosampler, the appropriate

position of the reference solution must be specified on the "SOLUTIONS"

page (see Soln.name).

Comments • The RADD>F instruction must be used in both the recording of the

calibration curve and in the determination.

• For recording of the calibration curve, the RADD>F instruction must be

located within a CAL loop.
