A step-by-step description of the reflectometric determination of sucrose (saccharose) in soft drinks using Reflectoquant® test strips and reflectometer, ideal for in-process control and on-site testing.
High performance, reliability, and reproducibility of HS-SPME in combination with GC/MS for the determination of VOCs in water was proven in an interlaboratory trial. The new ISO 17943 using HS-SPME is an improvement on existing official methods for this determination
Enzymatic methods for food analysis are highly specific and offer considerable time and cost savings over other methods, especially from the sample preparation standpoint. We offer a wide variety of convenient kits and reagents for rapid and reliable enzymatic food
This assay protocol is suitable for the colorimetric/fluorometric detection of Galactose and Lactose in cell and tissue culture supernatants, urine, plasma, serum, and other biological samples using the Galactose and Lactose Assay Kit (MAK011). In this assay kit, galactose is
Terpenes are present in essential oils derived from plants and often impart characteristic aromas to the plant or its oil. The SPME is a convenient, efficient, and easy to automate sample preparation technology for analyzing the terpene/terpenoid profile of these
The use of solid phase microextraction (SPME) allowed for the straightforward, fast, sensitive, and accurate GC/MS determination of the residual solvent content of spiked and unspiked samples of hemp extract.
Supelco's Z-Sep+ sorbent effectively removes fat and pigment interferences from avocado, with good pesticide recoveries; it removes more matrix than traditional PSA/C18 sorbent, and produces a lower background for GC-MS analysis.
This assay protocol is suitable for the colorimetric/fluorometric detection of Galactose and Lactose in cell and tissue culture supernatants, urine, plasma, serum, and other biological samples using the Galactose Assay Kit.
RP-Amide and HILIC, both amenable to the analysis of polar compounds, were successfully used to resolve several beverage components, including sugars, vitamins, sweeteners, preservatives, and caffeine.
