Glossary


Disposable aluminum dishes are used to hold the sample during testing so that the sample will be heated uniformly to achieve accurate results. The dish is discarded after every test to prevent contamination that could affect the accuracy of the reading. (DSC Part Number: 3065)
a methodology for determining moisture content that is accepted by the Association of Analytical Chemist (AOAC).
Duration of test is dictated by the definite amount of time as set by the user. Test will be over once the pre-set time is reached.
Duration of test is dictated by the rate of change of weight over time as set by the user. Test will be over once the pre-set rate of change in weight over time (Ex: 1mg/60 sec) is achieved.
program that allows the unit to be connected to a computer. This is also commonly known as the handshake software.
a fat tester that measures fat by automated processing of real time data from the equipment sensors using an algorithm that conforms with the approved AOAC methodology. This provides a more accurate reading by eliminating human error in the analog reading of machines using the drip method.
is a method of determining the fat content by letting the fat drip out of the sample while being heat-up. This methodology is not as accurate as using a digital fat tester.
calibration using a weight with known value, other than that of internally installed in the unit.
some design of testers offer a glass-free construction which eliminates the possibility of contaminating the product with pieces of broken glass. This feature is highly used in food processing facilities.
also known as a tungsten halogen, quartz-halogen or quartz iodine lamp, is an incandescent lamp that has a small amount of a halogen such as iodine or bromine added. This type of lamp offers a more uniform heating which is a factor in having accurate results. Likewise, it heats up and cools down fast making the heating process more efficient and reliable.
Infrared rays are electromagnetic waves (780 nm to 1mm) which come after visible light (380-780 nm) in the electromagnetic spectrum. People cannot see these rays but they are perceived as warmth.
Moisture Content is determined by the loss of weight as the material is subjected to heat. This method is also known as thermogravimetry . Moisture Content is computed by the difference between the Initial Weight and the Final Weight divided by the Initial Weight.
Determination of moisture content below 1% is considered as low moisture analysis. Plastic pellets that have undergone through the drying process contains very low moisture content.
Nuclear Magnetic Resonance (NMR) spectroscopy is an analytical chemistry technique used in quality control and research for determining the content and purity of a sample as well as its molecular structure. For example, NMR can quantitatively analyze mixtures containing known compounds. For unknown compounds, NMR can either be used to match against spectral libraries or to infer the basic structure directly. Once the basic structure is known, NMR can be used to determine molecular conformation in solution as well as studying physical properties at the molecular level such as conformational exchange, phase changes, solubility, and diffusion. In order to achieve the desired results, a variety of NMR techniques are available.
a weighing scale that is NTEP (National Type Evaluation Program) Certified can be classified as legal for trade. This means this scale can be used to weighing items at point of sale.
a weighing scale that is NFS (National Sanitation Foundation) Certified is suited for weighing food. This type of scale has features to ensure sanitation such as being water resistant so it can be wash down for cleaning.
portable printers are used to provide a recorded documentation of the test results.
is the number of decimal places is a readout. The more decimal places, the more accurate is the reading.
Glass fiber pads provide a useful medium for applying liquid samples. Dispersing the liquid into the fiber pad decreases sample surface tension and increases overall surface area which aids in achieving accurate results and shortening analysis time. (DSC Part Number: 1019 (9.0 cm dia.), 1001 ( 4x4 inch square).
determines the point at which measurement or the test will terminate The two most common setting is the constant time and the constant weight.
is the maximum weigh that the balance can accurately measure.
