Page 7: Connecting The Moisture Analyzer To Ac Power
Connecting the Moisture Analyzer to AC Power § Check the voltage rating and plug design $ The heating unit of the moisture analyzer has been factory-set to either 230 V or 115 V for technical reasons. The voltage has been set to the rating specified on your order. The voltage setting is shown on the manufacturer’s label (see the bottom of the analyzer), for example: – 230 volts: MA150–…230.. – 115 volts: MA150–…115.. If they do not match: Do not operate your moisture analyzer; contact your local Sartorius office or dealer. Use only – Original power cords – Power cords approved by a certified electrician – If you need to connect an extension cord: Use only a cable with a protective grounding conductor § Connecting the moisture analyzer, rated to Class 1, to power supply (mains supply): The moisture analyzer must be plugged into a properly installed wall outlet which has a protective grounding conductor (PE) Note: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense. Changes or modifications not expressly approved by Sartorius could void the user’s authority to operate the equipment. Safety Precautions... -

Page 21: Preparation
Preparation Adjustment to an Existing Measuring System Make sure you carry out the following A moisture analysis method often replaces another drying method (such as oven preparations prior to drying a sample: drying method) because it is simple to use and requires shorter analysis time. In this case, you should adapt this method to that of the moisture analyzer in order – Adjustment to the available measuring to obtain values comparable to those yielded by your standard reference method. system (if required) § Perform parallel measurements: take a fresh sample and divide it in half – Sample preparation § Determine the moisture content of the first half using your standard method of analysis – Setting the drying program parameters § Analyze the second half of the sample in the moisture analyzer. Use the following settings: – fully automatic mode for the shutoff parameter – lower temperature settings than for the oven drying method – temperature setting for organic substances: 80–100°C – temperature setting for inorganic substances: 140–160°C $ If the result of the second analysis does not correspond to that of the first: – repeat the analysis first using a different temperature setting – t hen use the semi-automatic mode for the shutoff parameter (for example with a different loss rate per 24 s) $ Vary the shutoff parameter if required: – Increase end-point recognition: set the parameter to 2 mg/24 s or 1 mg/24 s – Decrease end-point recognition: set the parameter to 10 mg/24 s or 20 mg/24 s... -
Page 22: Preparing A Sample
§ Take only one sample at a time for a given analysis and prepare it as quickly as possible. This way it will not lose or gain moisture as a result of the ambient conditions. $ If you need to take several samples simultaneously, the samples must be sealed in air- tight containers to ensure that the storage conditions do not alter the state or condition of the samples: – Warm or highly volatile substances lose their moisture very quickly. – S toring samples in a container may lead to moisture condensing on the walls of the container. – If the container is too large, moisture is passed to the air remaining in the container. $ Mix the condensed moisture back in with a sample, if necessary. Preparing a sample § When crushing a sample, avoid any contact with heat: Heat results in moisture loss. § Crush a sample with – a pestle – a shredder (see below) For liquids containing solids, use – a glass stirrer – a spoon, or – a magnetic stirrer. $ Use an appropriately designed tool for shredding a sample. Using disposable sample pans § Use only Sartorius disposable sample pans (inner diameter of 92 mm). Reusing sample pans leads to poor reproducibility of results for several reasons: – sample residues can remain on the pan even after cleaning – residues from cleaning agents can evaporate during the next moisture analysis – s cratches and grooves made during cleaning result in damage that forms points of attack for hot, rising air produced during the drying process (more pronounced buoy- ancy) - Page 23 Applying a Sample to the Sample Pan § Apply the sample to the sample pan in a thin, even layer (height: 2 to 5 mm, weight: 5 to15 g); otherwise: – a sample applied unevenly will result in a non-uniform distribution of heat – a sample will not be dried completely – the analysis time will be prolonged unnecessarily – the sample burns or a crust/ skin forms on its surface as a result of a very thick layer – t he crust makes it difficult or impossible for moisture to escape from the sample during the drying process – an uncertain and unknown quantity of moisture remains in the sample § Apply liquid samples, pasty samples or samples that can melt to a glass fiber filter (order no. 6906940); advantages include: – uniform distribution due to capillary effect – liquids prevented from beading together and forming drops – moisture can evaporate faster with larger surfaces – considerably more convenient than the “sea-sand method” When drying samples containing sugar, a crust or skin can form and seal the surface. A glass fiber filter is particularly useful in such cases. The moisture can evaporate downwards through the surface of the filter. You can prevent or limit crust/skin formation by placing the glass fiber filter on top of the sample. § Cover solid, heat-sensitive samples with a glass fiber filter (order no. 6906940); advantages include: – gentle heating; sample surface is shielded from excessive heat – higher temperature setting can be selected – uniformity of the sample surface – faster evaporation of the moisture – excellent reproducibility for samples containing fat Preventing the formation of crust/skin Solvents can be applied to the sample to prevent the formation of crust/skin during anal- ysis. The solvent applied has no bearing on the final result of an analysis.
