Solid waste pollution has become a major challenge in the field of environmental protection. BTEX (such as benzene, toluene, ethylbenzene, etc.), as typical organic pollutants, pose significant threats to the ecological environment and human health due to their high toxicity, strong mobility, and ...

As a nucleotide, Uridine 5'-monophosphate (UMP) is a pivotal intermediate in nucleic acid metabolism within living organisms. It is the most abundant nucleotide in mammalian milk, and the dietary requirement for uridylate is significantly higher than for other nucleotides during the growth and ...

Ammonium polyphosphate is also known as ammonium polypolyphosphate or condensed ammonium phosphate. Ammonium polyphosphate with a low polymerization degree features good water solubility, high nitrogen and phosphorus nutrient content, and a slow-release effect of its phosphorus element, making it ...

Spirulina can be divided into feed-grade, food-grade, and types for special purposes based on its application. Feed-grade spirulina powder is typically used in aquaculture and livestock farming, while food-grade spirulina powder is used in health supplements and added to other foods for human ...

The Evaporative Light-Scattering Detector (ELSD) is a novel mass detector with theoretical applicability to any compound that can form gaseous particles. The 2025 editionof the Pharmacopoeia specifies the use of Evaporative Light-Scattering Detection (ELSD) for the analysis and quality control of ...

The determination of BTEX in water was performed using an Anhui Instrument GC6100 gas chromatograph configured with a flame ionization detector (FID) and a headspace sampler, in accordance with the standard method "Water Quality—Determination of Benzene Homologues—Headspace/Gas Chromatography" (HJ ...

Dimethyl fumarate also known as (E)-2-butenedioic acid dimethyl ester, trans-butenedioic acid dimethyl ester, alternatively referred to as dimethyl maleate, commonly known as moldproof preservative Moldkiller No. 1, abbreviated as DMF.
