8-2. Technical tips

Here is the list of technical tips to help solve your measuring problems like
“Measurement does not end” or “The result is not stable”.

The result of density measurement mostly depends on sample character and
condition. Understanding the nature of density meter is the key for correct
measurement.

Sample type

Technical tips

Air bubble appears.

The air bubble is liable when cell temperature is
higher than sample. Warm the sample first.

Air bubble is formed.

The tube line leaks somewhere. After dried, overhaul
the joints and clean with tissue.

Air bubble is blended.

When sampling viscous liquid by pump, air bubble
may be blended. Use syringe instead.

Solid is deposited.

When  cell  temperature  is  lower  than  sample,
dissolved  substance  may  be  solidified.  Raise  cell
temperature to the same level as sample.
Concentration distribution may not be even in viscous
sample (e.g. sucrose). Carefully stir  sample  liquid  to
equalize concentration.
Repeatability of separated liquid is not stable.

The result is unstable.

When the solvent does not dissolve in sample liquid,
measurement result may not be stable with
contaminated measuring cell. Change the solvent.

Measuring time is long. If temperature compensation is not necessary, turn it

off to shorten measuring time.

Measuring time is long
with

viscosity

correction off.

Stability (measurement mode) may be set to zero (0).
Measurement time can be shortened if you set
stability to one (1). (Note that measurement accuracy
with stability 1 is ±0.0001g/cm

3

.)

Sampling by pump
takes a long time.

When the sample is highly viscous, sampling by pump
takes a long time. Use syringe instead.

It does not print out.

Digital configuration with printer may be wrong.
Refer to separate Function Description (6-9-3).
