StablCal, Formazin, SDVB, degrees or custom).
Measured with different
instrument type. Read
standard?
The verification standard was measured on a different type of instrument (e.g.,
different lasers).
Remove air bubbles from the sample
Air bubbles can cause unstable readings. Use a degassing method to remove air or other gases from
the sample before measurement even if no bubbles are seen.
The methods typically used for degassing are:
Let the sample stand for several minutes
Apply a vacuum
Use the sample degassing kit
Use an ultrasonic bath
Let the samples stand for several minutes, then gently invert two or three times before measurement.
In some cases, more than one method may be necessary to remove bubbles (e.g., the use of heat
with an ultrasonic bath may be necessary in some severe conditions). Use care with these methods
as sample turbidity can be changed if these methods are not used correctly.
Condensation
If condensation collects on the sample vial during measurement, let the sample become slightly
warmer before measurement. Keep the sample at room temperature or partially put the sample vial
into a warm water bath for a short time.
Note: A temperature increase can change the sample turbidity. Measure the sample before the temperature
increases when possible.
