The importance of Analytical Standards are evident in many research and development fields such as product and specification testing, quality control and technical service work. Taking into consideration the growing demand for analytical standards, the management of Alfa Chemistry decides to launch physical properties standards, a new product line of analytical standards, for clients across the globe. Analytical standards are used to confirm the presence of specific components in mixtures, to increase the precision of quantitative analysis, to perform a test or a calibration of an analyzer or for other purposes. The physical property standards are specially designed for testing physical properties, including but not limited to: density, melting point, conductivity, color, viscosity, particle size, refractive index, ion activity as well as turbidimetry. The selection of physical property standards can be applied in varieties of industries, such as chemistry, food and material science. These high quality standards aim to support the testing certainty, and at the same time enabling confidence in the integrity of both testing results and products analyzed. More specifically, the newly added physical properties standards at Alfa Chemistry cover the following sub-types: Acidity / TAN Standards Aniline Point Standards Viscosity Standards Cloud Point Standards Density Standards Distillation Flash Point Freezing Point Physical Properties CRMs Plugging Point Standards Quantitative NMR Total Suspended Solids X-Ray For third-party testing laboratories, analytical standards with a high level of accuracy are of great importance in the calibration of laboratory equipment so that first-class reliable analytical test data can be produced. Below are some of the physical properties standards provided by Alfa Chemistry: Acidity Standard (CAT AS212791), Aniline Point Standard (CAT AS212792), Smoke Point Standard (CAT AS28301), Density Standard (CAT AS212700), Distillation Standard (CAT AS28501), Flash Point Standard (CAT AS212778), Freezing Point Standard (CAT AS212789), Chlorine 37Cl (certified for isotope abundance ratio, CAT AS28801), CFPP Standard (CAT AS28901), Dimethyl terephthalate solution (CAS Number 120-61-6), Phosphonoacetic acid solution (CAS Number 4408-78-0), Dimethyl sulfone solution (CAS Number 67-71-0), Bruker quantitative PQ Certified Reference Material, etc. Each and every of the reference material or standard is supplied with a comprehensive certificate of analysis (CoA).
