Materials MASINT involves the collection, processing, and analysis of gas, liquid, or solid samples, is critical in defense against chemical, biological, and radiological threats (CBR), or nuclear-biological-chemical (NBC), as well as more general safety and public health activities.
[1] [2] The scope of the term often differs; some definitions limit the term's use to techniques which study the microscopic structure and properties of materials, [2] while others use the term to refer to any materials analysis process including macroscopic techniques such as mechanical testing, thermal analysis and density calculation.

It was founded in 1884 as the Association of Official Agricultural Chemists (AOAC) and became AOAC International in 1991. It publishes standardized, chemical analysis methods designed to increase confidence in the results of chemical and microbiological analyses. Government agencies and civil organizations often require that laboratories use ...
All analytical procedures should be validated. Identification tests are conducted to ensure the identity of an analyte in a sample through comparison of the sample to a reference standard through methods such as spectrum, chromatographic behavior, and chemical reactivity. [5] Impurity testing can either be a quantitative test or a limit test.
TGA – Thermogravimetric analysis; TIKA – Transmitting ion kinetic analysis; TIMS – Thermal ionization mass spectrometry; TIRFM – Total internal reflection fluorescence microscopy; TLS – Photothermal lens spectroscopy, a type of photothermal spectroscopy; TMA – Thermomechanical analysis; TOF-MS – Time-of-flight mass spectrometry
The gravimetric analysis involves determining the amount of material present by weighing the sample before and/or after some transformation. A common example used in undergraduate education is the determination of the amount of water in a hydrate by heating the sample to remove the water such that the difference in weight is due to the loss of ...
On 5 May 2021, Joko Widodo signed Presidential Decree No. 33/2021, effectively establishing BRIN as the sole national research agency and decreeing that all Indonesian national research agencies—such as the Indonesian Institute of Sciences (LIPI), the Agency for the Assessment and Application of Technology [] (BPPT), the National Nuclear Energy Agency of Indonesia [] (BATAN), and the ...
