Part III Model 6600
Teledyne Analytical Instruments
Manual Sample Introduction
Manual sample introduction is sometimes desired for the following rea-
sons:
1. Analyzer calibration.
2. Optical balancing on tap water, sea water, or zero water prepared from
the sample.
Prepare the system as follows:
1. Make sure that the instrument is in the analyze mode. The solenoid
valves are programmed to be deactivated so that the sample is con-
nected to the pump or take-off and sample cell.
2. Turn off the homogenizer.
3. Turn off the sample pump.
5.5.1 Required Calibration Equipment
The following laboratory accessories will be required to properly calibrate
the analyzer:
1. Blender: A Waring Model 1120 (or suitable equivalent) laboratory type
blender will be required to prepare the span calibration fluid.
CAUTION
Do not attempt to use the system homogenizer assembly to prepare the
span fluid. Correct control of the precise volumes required for the proper
preparation of the span fluid cannot be achieved with the system homog-
enizer.
2. Microliter Syringe. Microliter syringes or pipettes will be required to
prepare the span fluid.
3. Graduate. A 500 milliliter graduate will be required to measure the
precise volume of water used in the preparation of the span fluid.
