General test, just as its name implies, including some routine chemical and physical analytical measures, is quick and convenient. Nowadays, we are surrounded by all kinds of elements and substances, and their detection is inseparable from general analysis and separation. We can use traditional testing methods and instruments to measure the properties of materials and the fundamental performance of components, so that we can have an unmixed, transparent and healthy world.
Below is a list of our available general test services (include but not limited to the following):
In manufacturing, substances are most efficient when they're pure. Likewise, we always want to produce as pure organic matter as possible. One of the most common methods to determine the purity of a material is through analysis of the differential scanning calorimetry (DSC). Other methods used in testing the purity include melting and boiling point determination, gravimetry, titration, UV-VIS spectroscopy, nuclear magnetic resonance, and so on.
Structure characterization, when used in materials science, refers to the broad and general process by which a material’s structure and properties are probed and measured. In the last century, numerous useful characterization techniques have been developed and practiced, such as mass spectrometry (MS), ultraviolet-visible spectroscopy (UV-vis), Fourier transform infrared spectroscopy (FTIR), nuclear magnetic resonance spectroscopy (NMR).
During the manufacturing process or the stability study for an Active Pharmaceutical Ingredient (API) or drug product, a sample may be found to contain impurities, which might have side-effect. The technique best suited to isolating liquid impurities is high-performance liquid chromatography (HPLC), using high-pressure columns. The identification of impurities can use the mass spectrometry or other coupling techniques.
The counter ion, which also can be called as counter ion, is the ion that accompanies an ionic species in order to maintain electric neutrality. At present, more than 50 % of pharmaceuticals on the market using counter ions, so their analysis constitutes an essential part of drug development. Ion chromatography (IC) and ultra-high performance liquid chromatography (UHPLC) are the common analytical techniques.
Heavy metals are a subset of atomic elements that exhibit metallic properties, such as transition metals and other metalloid elements. In addition to general chemical analysis, there are many instruments that can be used to determine varieties of heavy metals, such as inductively coupled plasma optical emission spectrometry (ICP-OES) and atomic absorption spectrometer (AAS).
Thermal analysis, which is often used as a term for the study of heat transfer through structures, is a branch of materials science where the properties of materials are studied as they change with temperature. There are numerous methods are available at BOC Sciences, such as dielectric thermal analysis (DEA), differential thermal analysis (DTA), etc.
Elemental analysis is a process where a sample of some material is analyzed for its elemental and sometimes isotopic composition. Some common elemental analytic methods include combustion analysis, gravimetry, optical atomic spectroscopy, neutron activation analysis.
X-ray powder diffraction (XRD) is primarily used for phase identification of a crystalline material and can provide information on unit cell dimensions. By using the X-ray diffractometers, we can identify unknown crystalline materials.
