5.4 Determine melting points or melting ranges
5.4.1 Prepare samples
When you prepare the samples, pay attention to the rules listed below.
• The amount of substance is the same across all capillaries. Slight differences in the amounts could
cause deviations in the measured melting point temperatures.
• The melted substance still covers the hole for transmission light.
We recommend using capillaries from METTLER TOLEDO for compliance with standards.
5.4.1.1 Prepare samples of solid substances
In the following procedures, a sample height of 3mm is used. If you need to use a different height, you
need to adjust the procedure.
Prepare the substance
1 If your sample is moist, dry it in a desiccator.
2 If you have a coarse crystalline substances, grind it in an agate mortar to a fine powder.
Fill the melting point capillaries without the sample preparation tool
The substance and melting point capillaries are dry.
§
The substance is a fine powder.
§
1 Press the open end of the capillary into the substance.
Operation16Melting Point Excellence System
Page 19
2 To move the substance to the bottom of the melting point capillary, turn
1
over the melting point capillary and tap the bottom of the melting point
capillary on a hard surface.
ð The substance slides to the bottom of the capillary.
3 If the sample does not move to the capillary bottom, you can run the
bottom of the capillary along the ribbed part of tweezers or tamp it down
using a minimum amount of force with the tamping wire supplied.
4 To compact the substance tap the bottom of the melting point capillary
several times on a hard surface.
ð The substance is compacted.
5 Check the sample height with a ruler.
6 If the sample height is less than 3mm, repeat the steps above.
ð 3mm of compacted substance fill the bottom of the melting point capillary.

§
1 Press the blue(1) and the gray part together and insert the closed end
of the melting point capillaries you need to fill with the same
substance into the sample preparation tool.
2 Make sure that the open ends of the melting point capillaries are on
the same height.
3 Turn over the sample preparation tool and press the open ends of the
capillaries into the substance.

turn over sample preparation tool and hold it about 10mm above a
hard surface and press the blue(1) and the gray part together.
ð The capillaries fall towards the hard surface and bounces up and
down a few times.
ð The substance slides to the bottom of the capillary.
5 Press the blue(1) and the gray part together and lower the sample
preparation tool to the surface.
ð The melting point capillaries are pushed up into the sample prepa-
ration tool.

ð 3mm of compacted substance fill the bottom of the melting point
capillary.
5.4.1.2 Prepare samples that decompose, sublime or vaporize
When a sealed capillary is heated, the volatile components evolved by the sample produce an over
pressure that might inhibit further decomposition or sublimation.
The melting point capillary is filled with the substance.
§
1 Make sure that the upper part of the melting point capillary is free from sample.
2 Seal the melting point capillary in a gas flame properly and rapidly.
5.4.2 Run an analysis using a manual method
The following procedure shows you how to run an analysis using an indirect shortcut. The procedure is
based on an example. Some steps may differ if the manual method you use is configured differently.

ð No cleaning agent can enter the instrument.
3 Moisten a soft cloth with water and a mild detergent.
4 Clean the housing with the soft, slightly moist cloth.
5 Dry off any residual moisture.
6 Turn the metal lid to the position.
7 Reconnect the instrument to the power supply and switch on the instrument.
ð The instrument housing is clean and the instrument ready for your next analyses.
6.2.2 Clean the insulation glass, the capillary guide and the transmitted light holes
To prevent false readings, the insulation glass should be checked regularly and cleaned as needed.
Particles and smudges on the insulation glass can block the light, cause bothersome spots in the pictures
or cause false readings.
Clean the insulation glass, if the light does not appear homogeneous and bright for all holes.
Occasionally, tiny particles can fall into the capillary guide or glass splitters of broken capillaries can
remain in the capillary guide. This debris can either result in black spots in the videos or prevent adequate
light exposure for the substances under investigation. In most cases, you can remove this debris.
The following chapters describe how to remove and reinstall the insulation glass and the capillary guide
and how to clean the parts.

6.4 Check the temperature accuracy of the instrument
To check if the temperature accuracy of your instrument is still within the specified tolerance limits, you need
to perform a calibration. To perform a calibration, you run a melting point method for a reference substance
and compare the results with the values on the Certificate of Analysis of the reference substance.
Perform the calibration
A shortcut for a calibration method for the relevant reference substance is available.
§
The tolerance limits for the reference substance are defined.
§
1 Run an analysis using the appropriate calibration method.
2 Check if the mean value of the analysis lies within the tolerance limits for the reference substance.
3 If the calibration results are not within the tolerance limits, inform the person responsible for the
adjustment of the instrument.
