Cannabis testing: In-house prepared water as an alternative to bottled HPLC-grade water

24 Nov 2022

In many testing laboratories, bottled HPLC-grade water is the standard when performing quantitative potency analysis for cannabinoids like THC (Tetrahydrocannabinol) or CBD (Cannabidiol). However, in-house produced water may be a qualitatively equivalent and more cost-effective alternative.

Arium® Pro Type I Ultra Pure Water Systems

Sartorius Group

Arium® Pro Type I ultra pure water systems for the production of reagent-grade water needed for critical applications as well as routine analyses. Typical applications are the production of ultrapure water for cell culture or chromatographic applications. The Type I ultrapure water systems are available in four different versions and can be ordered as wall-mounted unit, bench-top system or built-in system. Arium® Pro features a convincing innovative design, quality and ease of use. Sophisticated display and menu functions User can choose between three Comfortable water dispense setups Highly developed electronic features Display and menu functions The innovative glass operator interface with touch function can be operated easily. The intuitive menu navigation with integrated text support is easy to handle. Pre-setting of relevant parameters for documentation, e.g. conductivity feed and product PIN protected menu and service setting Service and alarm functions supported by graphic presentation Color-coded warnings Displays measured values for water (feed water, product water, temperature, total dispended water), system information and count down for next recommended consumable replacement. Integrated totalizer to monitor water consumption Diary function Water Dispense With the manual, volume and time dispensed water control the Arium® pro gives users the greatest possible flexibility in routine applications. A countdown for the remaining amount of water is displayed and the system comes with a volume and time memory function. Manual dispense (stepless from 0,5 up to 2 l/min) Volume dispense (0,1 – 60 l) Time dispense (30 sec – 59 min) Electronic features for data backup and display Arium® Pro automatically measures the conductivity of feed and product water. These and other parameters can be displayed continuously or directly on a PC or printer and can be saved on a SD card as well. Related products Arium Smart Station Arium® Mini

UHPLC and HPLCHigh performance liquid chromatography (HPLC) and ultra high performance liquid chromatography (UHPLC), also known as UPLC, are analytical techniques used to separate, identify and quantitate components of complex mixtures including biological samples such as proteins and lipids as well as chemical mixtures of pesticides, drugs and oils. Both techniques are liquid chromatographic methods but differ by operating pressures (HPLC < 6000 psi < UHPLC ). Components of HPLC and UHPLC systems include columns, detectors, pumps, autosamplers and column heaters. Explore a range of UHPLC and HPLC columns for your specific sample needs including reverse phase, normal phase, ion exchange, HILIC, ion exclusion and size exclusion columns. For more specialized HPLC, explore FPLC, countercurrent LC and simulated moving bed systems. Find the best UHPLC and HPLC equipment in our peer reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.LC-MSLC-MS (liquid chromatography-mass spectrometry) systems and equipment are used for separation and quantitative analysis of complex mixtures, combining liquid chromatography and mass spectrometry. Quantify proteins, contaminants, pesticides or screen for drug metabolites with a high level of sensitivity. LC-MS systems and equipment include reverse phase, normal phase and specialized columns integrated with various MS detectors such as time-of-flight (TOF), quadrupole, orbitrap or ion trap mass analyzers. LC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzer give greater sensitivity and resolving power to your analysis.
