5.8 Methods parameters defining temperature segment and evaluation
A method contains the parameters and data required to run an analysis of a particu lar substance. An analysis of a substance can easily be repeated by using the same method. Among other things, the parameters in the method define the temperature segment, the type of evaluation (melting range or melting point evaluation can be specified) and the behavior of the measuring cell at the end of an analysis.
administrative infor mation
Data of administrative nature such as an identification string, a title and a creation and modification date is also included in the method. A commenting text on the method itself and information on the standard operating procedure (SOP) in which the method is to be used can be entered.
protection, calibration
It is possible to protect a method so that it can only be changed by the user that cre ated it or by the administrator. By including a reference to a standard calibration sub stance, a method can easily be used to calibrate the instrument. Regular methods are stored on the instrument. They can be edited at any time to change the parameters, if required. An existing method can be used as a template to create a new method. Apart from regular methods there are so-called manual methods that can be used to quickly run an analysis. Only a restricted number of parameters can be defined which however can all be edited in a single dialog. Regular methods can be created in three ways: ● You can convert any manual method into a regular method. ● You can use an existing method as a template, change it and save it under a
new name. ● You can create a new method "from scratch".
5.9 Manual methods A manual method contains the parameters and data required to run an analysis of a particular substance. An analysis of a substance can easily be repeated by using the same manual method. Among other things, the parameters in the method define the temperature segment, the type of evaluation (melting range or melting point evalua tion can be specified) and the behavior of the measuring cell at the end of an analy sis. Furthermore, a commenting text on the method itself can be entered.

Performing an Analysis
6 Performing an Analysis 6.1 Sample preparation The key to good results is careful and exact sample preparation. Prepare your samples so that the amount of substance is the same across all capil足 laries. Slight differences in the amounts could cause deviations in the measured melting point temperatures. It is also important that the melted substance still covers the hole for transmission light. Therefore, try each substance with different fill heights to ascertain the best amount of solid substance for further testing. Number of samples Experience has shown that it is best to measure a minimum of three samples of the substance under investigation in parallel. This provides you with the possibility to calculate statistics based on the results. Using a fourth capillary is beneficial should one of the samples be unknowingly problematic. You do not have to repeat the analysis, because you still have three good results. This, of course, saves time, money and energy. See the section "Glass capillary tube standards" in the "Appendix" for information about the different international norms.
6.1.1 How to prepare samples - solids The diagrams below show how to fill the capillaries.
Moist samples have been dried in a desiccator; capillaries should also be stored in a desiccator.
MP70
25
Performing an Analysis
Coarse crystalline substances are finely ground (in an agate mortar). a) Fill the capillary - Add the powdered samples to sample capillary tubes to a height of 2.5 to 5 mm (or according to your Pharmacopeia - see "Glass capil lary tube standards") by pressing the open end of the capillary into the sub stance. To compact the substance, turn over the capillary and tap the bottom on a hard surface. Reproducible sample compaction is also possible by allowing the capil laries to fall to the bench through a tube of 1 m in approximate length. 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. (see pictures above) Alternatively, you can use the innovative METTLER TOLEDO sample preparation tool (see pictures below - Checking capillary fill height): place the capillaries in the sample preparation tool and let them drop simultaneously onto a hard sur face.
b) Check the capillary fill height - Check the fill height using the lines marked on the sample preparation tool. For accurate measurements, the optimum fill height of 3-4 mm should be observed. A minimum fill height of 2.5 mm is required. The sample preparation tool offers many possibilities for checking the fill height of your substance. See the three dia grams below for estimating the various fill heights. For best results, the liquified substance needs to cover the holes for transmitted light.

6.1.2 How to prepare samples - fats and waxes Fats and waxes should normally not be pre-melted in order to avoid "wrong" mea足 surement results owing to the frequent appearance of metastable modifications.
MP70
27
Performing an Analysis
a) Press an open capillary (for example, break off the fused end of a normal melt ing point capillary) into the substance until it is filled to a height of 3 to 5 mm. b) Prevent the sample from running out of the capillary by adding a layer of sealer 1 mm thick (for example, "Sealant Pad", cat No. B8900-27, from Cardinal Health, Dublin, OH 43017) or in an emergency with some chewing gum.
6.1.3 How to 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 inhibits further decomposition or sublimation. a) Make sure that the upper part of the capillary is free from sample. b) Seal the capillary in a gas flame properly and rapidly.
6.2 Rules for the most important measurement parame ters Please consider the four rules below before starting an analysis. 1. Heating rate Usually, and typical for most Pharmacopeias, 1 °C/min. For highest accuracy and non-decomposing samples, we recommend 0.2 °C/min. With substances that decompose, we recommend 5 °C/min, for exploratory measurements 10 °C/min. 2. Start temperature 3 to 5 minutes below the expected melting point temperature (3 to 5 times the heat ing rate). Example: Benzoic acid (expected melting point temperature 122 °C) 122 °C - 5 min x (1 °C/min) = 117 °C 3. End temperature If you need a well-resolved measuring curve, we recommend an end temperature which is approx. 3 to 5 min. above the expected effect. Example: Benzoic acid (expected melting point temperature 122 °C) 122 °C + 5 min x (1 °C/min) = 127 °C 4. Melting point capillaries If at all possible, we recommend using capillaries from METTLER TOLEDO to guaran tee perfect tau lag correction. (see the sections "Parts and accessories" and "Glass capillary tube standards" for details about international capillary norms). Other capillaries with a diameter of up to 1.75 mm can also be used.

9.6.4 Printers Three types of printer devices can be installed, depending on the MP instrument model, output (paper, PDF) or network availability: printer types
● USB Compact Printer: a robust and easy-to-operate matrix printer which prints
onto standard quality paper rolls. ● PDF Writer: can be connected for PDF output (Storage location can be selected:
a USB memory stick or an SD card [cannot be used on the MP50]). ● Network Printer: can be connected to the ethernet interface of the MP instrument,
either by installing the printer in the network or using a switch. ESC/P 2 and PCL compatible printers from various manufacturers are supported (ethernet interface only!). Two types of configuration options are supported for obtaining IP address es automatically (dynamic) or setting it manually (static). The following table provides an overview of which printer combinations are possible with the different MP instruments.
