Viscosity R&D

This test method is a procedure for the measurement of viscosity of liquids using a digital rotary viscometer. This method can capture data points at a multitude of temperatures, rotational speeds, and rotor diameters, and is especially effective for data determination in non-Newtonian fluids

USP Organic Impurities in Ethanol [GC]

This USP test for Organic Impurities in Ethanol is a quantitative analysis performed using Gas Chromatography (GC) to detect and measure trace organic impurities in ethanol. These impurities may arise from the manufacturing process or raw materials and can affect the safety and quality of ethanol used in pharmaceutical applications. This test method quantifies acetaldehyde… Continue reading USP Organic Impurities in Ethanol [GC]

Vitamin B-9

This test method quantitatively analyzes vitamin B-9 (folic acid) in complex food and supplement matrices using UPLC-MS technology. By combining UPLC separation with mass detection, this method achieves superior sensitivity and selectivity compared to UV-only approaches, enabling reliable biotin quantification even at trace levels.

Vitamin D

This test method provides a refined UPLC–MS/MS method that improves accuracy and robustness when measuring vitamin D in food matrices.

Volatile Acids

This test method is used to determine the concentration of volatile fatty acids (VFAs), such as acetic, propionic, and butyric acids, in wastewater, anaerobic digesters, and other biological treatment systems.

USP Nonvolatile Residue in Ethanol

This USP test for Nonvolatile Residue in Ethanol is a purity test designed to measure the amount of residual matter that remains after ethanol is completely evaporated. It helps assess the cleanliness and purity of ethanol used in pharmaceutical and laboratory applications.

Vitamin B-7

This test method quantitatively analyzes vitamin B-7 (biotin) in complex food and supplement matrices using UPLC-MS technology. By combining UPLC separation with mass detection, this method achieves superior sensitivity and selectivity compared to UV-only approaches, enabling reliable biotin quantification even at trace levels.

USP Potassium Chloride Assay

This USP test for Potassium Chloride Assay is a quantitative test used to determine the amount of potassium chloride (KCl) in a sample, ensuring it meets the purity and potency standards set by the United States Pharmacopeia (USP).

USP Ultraviolet Absorption of Ethanol

This USP test for Ultraviolet (UV) Absorption of Ethanol test is a spectrophotometric method used to assess the purity of ethanol by measuring its absorption of ultraviolet light at specific wavelengths. This test helps ensure that ethanol used in pharmaceutical and laboratory settings is pure and free from contaminants that absorb UV light, maintaining product… Continue reading USP Ultraviolet Absorption of Ethanol

Vitamins A & E

This test method provides a refined UPLC–MS/MS method that improves accuracy and robustness when measuring vitamins A & E in food matrices.
