DBS-BA-e-1311 29
5.5 Commissioning
In order to obtain exact results, the appliance must have reached its operating
temperature (see warm-up time chap. 1).
For this warm-up time the appliance must be connected to the power supply.
The accuracy of the appliance depends on the local acceleration of gravity.
Strictly observe hints in chapter Adjustment.
5.6 Connection of pe r i pheral devices
Before connecting or disconnecting of additional devices (printer, PC) to the data
interface, always disconnect the moisture analyser from the power supply.
Only use accessories and peripheral devices by KERN, as they are ideally tuned to
the appliance.
30 DBS-BA-e-1311
6 Adjustment
6.1 Adjust balance
As the acceleration value due to gravity is not the same at every location on earth,
each balance must be coordinated - in compliance with the underlying physical
weighing principle - to the existing acceleration due to gravity at its place of location
(only if the balance has not already been adjusted to the location in the factory). This
adjustment process must be carried out for the first commissioning, after each
change of location as well as in case of fluctuating environment temperature. To
receive accurate measuring values it is also recommended to adjust the balance
periodically in weighing operation.
• Observe stable environmental conditions. A warming up time (see chapter
1) is required for stabilization.
• Carry out adjustment with placed sample dish. Ensure that no objects are
within the sample dish.
• Carry out adjustment as near as possible to the balance’s maximum
weight (recommended adjustment weight see chap. 1). Weights of
different nominal values (10g – 60g) may be used for adjustment but are
not optimal for technical measuring. Info about test weights can be found
on the Internet at: http://www.kern-sohn.com

12 General information concerning moist ure analysis
12.1 Application
In all cases where moisture is added to or removed from products, a fast
determination of the moisture content is of enormous importance. For countless
products the moisture content is not only a quality feature but also an important cost
factor. Very often fixed limits for moisture content apply to the trade in industrial or
agricultural goods as well as chemical or food products which are defined by terms of
delivery and general standards.
12.2 Basics
Moisture does not only mean water but includes all substances that evaporate when
heated up. In addition to water this includes,
- Fats
- Oils
- Alcohol
- Solvent
- etc...
There are various methods to analyse moisture in a product.
KERN DBS uses a method called thermogravimetrics. In accord with this method,
the sample is weighed before and after heating, determining the material moisture by
looking at the difference.
The conventional drying chamber method follows the same principle, with the
exception that this method requires a considerably longer measuring period. . In
accord with the drying chamber method, the sample is heated from the outside to the
inside by a hot air current, so as to remove the moisture. The radiation applied in the
KERN DBS penetrates mainly the sample in order to be transformed inside it into
heat energy that is, warming from the inside to the outside. A minor amount of
radiation is reflected by the sample, a reflection that is less in dark samples than in
light-coloured ones. The depth of penetration of the radiation depends on the
permeability of the sample. In samples of low permeability the radiation only
penetrates the outer layers of the sample, possibly resulting in imperfect drying,
incrustation or burning. For that reason the preparation of a sample is of great
importance.
12.3 Adjustment to existing measuring method
Quite frequently the KERN DBS replaces a different drying method (such as a drying
chamber) as the KERN DBS achieves shorter measuring times during a simplified
operation. For that reason the conventional measuring method must be matched to
the KERN DBS in order to achieve comparable results.
• Carry out parallel measurement
Lower temperature setting for KERN DBS than drying chamber method
• Result of KERN DBS does not match reference
- Repeat measurement with changed temperature setting
- Vary switch-off criterion
DBS-BA-e-1311 75
12.4 Preparing a sample
Preparing a sample from solids:
• fast evaporation due to a greater surface
Prepare one sample at a time for measuring. This prevents the sample from
exchanging moisture with its surroundings. If several samples have to be taken at the
same time, they should be packed in airtight boxes so that they do not undergo
changes during storage.
To receive reproducible results, spread the sample thinly and evenly on a sample
dish.
Patchy spreads will produce inhomogeneous heat distribution in the sample to be
dried resulting in incomplete drying and increased measuring time. Sample clusters
generate increased heating of the upper layers resulting in combustion or
incrustation. The high layer thickness or possibly arising incrustation makes it
impossible for the moisture to escape from the sample. Due to this residual moisture,
measured results calculated in this way will not be comprehensible or reproducible.
• Spread powdery or grainy samples evenly on the sample dish.
• Grind coarse samples using a mortar or a shredder. When grinding the sample avoid
any heat supply as this may cause loss of humidity.
Preparing a sample from liqui ds:
For liquids, pastes or melting samples we recommend to use a glass fiber filter. The glass
fiber filter has the following advantages:
• Even distribution thanks to capillary attraction
• no formation of droplets
76 DBS-BA-e-1311
12.5 Sample material
Easy to determine are usually samples with the following characteristics:
- Grainy to powdery, pourable solids
- Thermally stable materials, emitting the moisture to be determined easily
without other substances evaporating at the same time
- Liquids that vaporize to leave a dry substance without developing a film
Difficult to determine may be samples that are:
- Glutinous or sticky
- Become incrusted easily or tend to form a film
- Decompose easily under the influence of heat or emit various elements
12.6 Sample size / originally weighted in quantity
Drying times, as well as achievable accuracy, are significantly influenced by sample
distribution. In the course of this arise two opposed requirements:
The lighter the originally weighted in quantity, the easier it is to achieve shorter drying
times.
However, the heavier the originally weighted in quantity, the more accurate a result.
DBS-BA-e-1311 77
12.7 Drying temperature
Bear in mind the following factors when setting the drying temperature:
Surface of the sample:
Compared with powdery or grainy samples, liquid and spreadable samples have a
smaller surface for the transmission of heat energy.
The use of a glass fibre filter improves the heat application.
Colour of sample:
Light-coloured samples reflect more heat radiation than dark ones and therefore
require a higher drying temperature.
Availability of volatile substances:
The better and faster the water or other volatile substances can be disposed, the
lower a drying temperature is required. If water is difficult to get to (e. g. in
synthetics), it has to be calcined at high temperatures (the higher the temperature,
the higher the water vapour pressure).
Results equivalent to other moisture analysing methods (e. g. drying chamber) can
be achieved by experimentally optimising the setting parameters such as
temperature, heating level and shutoff criteria.
12.8 Recommendations / Guidelines
Prepare standard sample:
- Crush sample, as required, and spread it evenly in the aluminium dish.
Prepare special samples:
- For sensitive or hard to spread test materials (e. g. mercury) a glass fibre filter
is available for use.
- Apply the sample equally on the glass fibre filter and cover it with a second
glass fibre filter.
- The glass fibre filter is also useful as a protection when splashing materials
are dealt with (each splash falsifies the final result).
