Porvair Sciences reports on a highly effective protocol, using its Plant Genomics microplate, for preparing cannabis samples for analysis of Tetrahydrocannabinol (THC) and Cannabidiol (CBD). With increasing legalization of cannabis for medicinal and research purposes, demand for accurate and high throughtput analysis of its active ingredients has dramatically risen. Cannabis plant material contains several cannabinoids for which the human brain has evolved receptors....

Waters Corporation has introduced a new amino acid analysis kit that reduces the time required to quantify amino acids, a critical application for research scientists investigating the physiological underpinnings of disease. The new Kairos™ Amino Acid Analysis Kit consisting of reagents, standards, an analytical column and associated methodology is capable of cutting analytical run times that can range up to two hours to run times of 10 minutes or less....

Testa Analytical Solutions e.K reports that its Nanobrook ZetaPALS zeta potential analyser is uniquely optimised to make sensitive and precise measurements in both organic and aqueous media. Typically making zeta potential measurements in organic (non polar) solvents requires much higher sensitivity than in aqueous (polar) solutions. The Nanobrook ZetaPALS analyser achieves this using phase analysis light scattering...

Labs can have a fragrance which is characteristic of a build-up of trace vapours. Ideally, the lab should not smell; however, in an environment in which automated analysis equipment continuously runs, the likelihood of organic chemical and reagent volatiles leaking increases. This concoction of substances in the air can not only be a fire and explosion risk, but can also be harmful to health. VapLock closed systems make it easy to improve laboratory safety by reducing exposure to vapors and hazardous solvent waste.

Restek has expanded its line of LC accessories to bring you even more of what you need to keep your LC flowing. Over 140 new items are now available, including fittings, tubing, mobile phase management and safety supplies, and more. Featured products include bottle top inlet valves to protect your lab from volatile compounds and your mobile phase from bacterial contamination, outlet valves to regulate pressure during helium sparging, and safety exhaust filters with a color indicator to clearly show when a changeout is needed.

Metrohm is proud to continue its productive collaboration with USP (the United States Pharmacopeia) on a global initiative to modernize monographs that have traditionally featured wet chemistry methods. The goal of this modernization initiative is to replace the methods in these monographs with selective and sensitive methodologies that reflect recent innovations and technology updates. Method innovations coupled with new instrumentation will make laboratory workflows more efficient and cost-effective....

Testa Analytical Solutions e.K. has added the AYE Differential Refractometer to its existing line of high-performance instruments for chromatographic measurements. The AYE is a flexible differential refractometer that may be used in either static or dynamic mode. In static mode, the specific refractive index increment (dn/dc) of dissolved samples can be easily and precisely determined in just a few minutes....

One of the main goals of the USP monograph modernization initiative is to replace non-specific methods with highly selective and sensitive instrumental analysis methods. Based on a joint project with Metrohm, the USP proposes a new ion chromatography method for chloride and sulfate detection in drug substances, potassium carbonate, and potassium bicarbonate. The method is described in a free technical poster....

Soltec was founded in 1982 by Jim Berray and grew to become one of the most respected manufacturers of septa and caps for use in chromatography workflow solutions. Sadly Jim passed away in 2017, but his team continued their dedicated work, building on their solid foundation of expertise in silicone chemistry, materials technology and production automation. Chief Executive Officer of Trajan, Mr Stephen Tomisich, comments, “We are pleased to welcome the Soltec team into the Trajan family....

Available with pore sizes of 90 Å for small molecule analysis and 1,000 Å for biomolecule analysis, each column in the toolkit can be screened under the same mobile phase conditions to help you develop your ultra-fast separation quickly and efficiently....

The new Finneran Full Recovery R.A.M., 9mm, vials are manufactured from Type I, Class A 33-expansion borosilicate glass. Finneran Full Recovery Vials deliver maximum sample capacity with minimal residual volume.  Use bottom or side draw-port needles. Unique chromatography sample vials and closures manufactured by J.G. Finneran Associates are available internationally from a network of laboratory dealers...

Testa Analytical Solutions e.K reports on how automation of isoelectric point measurement can be achieved using a BI-ZTU autotitrator in combination with a Nanobrook zeta potential analyzer. The stability of a dispersion is commonly determined by zeta potential. However, the surface chemistry of solid particles in a dispersion can be modified by altering parameters such as pH, surfactant concentration and salt concentrations....

Waters Corporation introduced the RenataDX™ Screening System, a flow-injection tandem mass spectrometry (FIA-MS/MS) system for rapid high-throughput analysis of extracted dried blood spots and other human biological matrices. “Waters has long been a trusted specialty measurement partner for mass spectrometry in the clinical laboratory. Continuing that history of purposeful innovation, the RenataDX Screening System is designed to ensure ease of use in clinical situations where system performance is critical...
