9. USP WATER PURITY MONITORING

9-1.

What is USP ? 

USP stands for United States Pharmacopeia and it is responsible for issuing guidelines for the pharmaceuti-
cal industry.  Implementing these guidelines is highly recommended for companies wishing to market drugs
in the US. This means that USP is important for pharmaceutical companies worldwide. USP recently issued:
- USP - recommendations for conductivity measurement. This new USP, aims at the replacement of 5 anti-
quated laboratory tests by simple conductivity analysis.

What is conductivity measurement according to USP?

Life would be easy, if the limits for the conductivity of injection water were set to be 1.3 µS/cm at a refer-
ence temperature of 25°C.  However, the committee (PHRMA WQC) who made the USP recommendations,
could not agree on a simple Sodium Chloride model for water quality determination.  Instead, they chose a
Chloride-Ammonia conductivity-pH model in water atmospherically equilibrated (CO2) at 25 °C.

The objective of the WQC was to find an easy way to establish the water quality, so on-line analysis at
process temperature was a necessary requirement.  However, if it is not possible to choose one tempera-
ture response model to work to, then it is also not possible to choose one temperature compensation algo-
rithm.

We as a manufacturer of analytical equipment do not want to go into the details of whether the limiting

conductivity values for water quality are based on the Chloride model or the Ammonia model.  Our job is to
develop on-line analyzers that make it simple for our customers to meet the water quality that is specified as
“stage 1: Conductivity Limit as a Function of Temperature.”

If the water exceeds the limits of stage 1, then it can still be acceptable, but requires the customer to pro-
ceed to Stage 2, and possibly Stage 3, to validate the water quality.  It is our objective to assure that our
customers do not exceed the limits in stage 1 to avoid them having to carry out the complicated laboratory
checks in Stages 2 and 3.

USP in the SC202

1. In SC202 we have defined an Error Code: E13. This is independent of what range the customer is mea-

suring or what temperature compensation method he is using for water quality monitoring. When the dis-
play shows E13, then the water quality exceeds the USP limits, and the FAIL flag on the display is acti-
vated to signal that the system needs urgent attention.

2. We have introduced uncompensated conductivity in the DISPLAY menu. In the LCD display the user can

read the temperature and the raw conductivity to compare his water quality with the USP table.

3. We have kept all the EXA functionality: It is even possible to have the mA Output and Display readings in

resistivity units.  Most users will have very good water quality and in the resistivity mode they will have
better resolution on the recorder or DCS.  The readings are simply the reciprocal values of the conductivi-
ty values.  In the example mentioned above the contact will close at an uncompensated resistivity of
1/1.76 µS/cm. = 0.568 M
