Transforming nitrite screening in pharma
New York cannabis pesticides kit simplifies testing
Introducing Restek’s New York Cannabis Pesticides Kit, a comprehensive solution for cannabis testing labs that includes 70 essential compounds, eliminating the need for in-house standard preparation.
With eight carefully designed ampuls, you can create a high-concentration working standard, providing greater analytical flexibility when constructing calibration curves and spiking sample matrices.
The kit is specifically formulated for the New York cannabis pesticide residue list, ensuring optimal stability and usability to guarantee the accuracy of your calibration standards.
Restek offers two independently produced lots from its ISO-accredited labs to meet your stringent quality control requirements.
Pharmaceutical manufacturers face the demanding and complex task of controlling nitrosamine levels within their product lines. One of the most effective ways of managing this is to control the levels of nitrites within the product. However, a quick and effective method for establishing the level of nitrite content present down to very low ppb levels has proved challenging with existing technology and methods.
The Automated Total Nitrosamine Analyser (ATNA) from Ellutia, can help pharmaceutical companies tackle this challenge. Whilst most commonly used for nitrosamine screening, The ATNA can also rapidly screen for total nitrite content down to low ppb levels.
The System can handle a wide range of sample types with minimal sample preparation. Samples are placed into headspace vials along with a reagent mixture. The Robotic Autosampler then performs the chemical reaction, and the headspace is sampled and directly injected into the Ellutia TEA Detector. This means there is no separation of compounds, and a single result for total content is produced. Specifically developed SPE cartridges can be used to differentiate between signals from nitrosamine and nitrite compounds.
The ATNA allows users to rapidly screen samples for both nitrosamine and nitrite content, giving greater confidence and visibility of where potential issues may be. Allowing them to focus resources where it really matters.

Innovative dual detector elevates GPC/SEC analysis
Testa Analytical has redefined the standards for demanding GPC/SEC applications, particularly in the study of polymer structure and branching, with the COMBO-ONE Viscometer/DRI detector.
Traditional viscometry detectors in GPC/ SEC, employing a configuration resembling a Wheatstone bridge with four matched capillary tubes, have been in use for many years but suffer from operational and performance limitations.
Carlo Dessy, the mind behind the COMBO- ONE, explained: “Our dual detector eliminates the fundamental drawback of traditional online viscometer design known as ‘sample breakthrough’ after each measurement. This innovation allows for much faster sample sequencing, effectively doubling the daily throughput of a GPC/SEC System. Additionally, it significantly reduces solvent and waste production.”
The COMBO-ONE Viscometer/DRI detector is fully compatible with all modern GPC/SEC systems.

Best practice zero solvent emissions in your lab
Solvent emissions cause many occupational diseases, breakdowns, and malfunctions. Especially in instrumental analysis, failures can be costly if they result in interruptions and maintenance work. SCAT Safety Caps block solvent vapours and ensure clean, reliable analysis. It has never been so easy to protect your health and save costs at the same time.
The SCAT system blocks solvent vapours and keeps your eluents clean. It protects your health, environment and quality of your analytical results. The mixing ratio of your solvents stays stable, as there is no evaporation.
Workspace safety and risk of solvent vapours: solvent vapours are toxic, flammable, and harmful to health. They escape even through smallest openings and leaks. During long-time exposure, even small concentrations in the laboratory air can cause serious health risks and damage.
Hermetically closed systems reduce emissions to zero: when extracting the eluent, the SCAT air valve ensures safe pressure equalisation to avoid underpressure during HPLC operation. On the waste side of your HPLC, the exhaust filter avoids overpressure inside the collecting container, and adsorbs vapours of solvents, acids and bases with a mix of 3 types of activated carbon.
The easiest way to ensure safety and quality for your HPLC lab: the SCAT System can be installed with a minimum of effort and cost, compared to the hassle of installing ventilation systems for each workplace. Discover the solution and upgrade your laboratory now to the latest safety standards.
