Analysis of aqueous mobile phase sample preparation and filtration steps in cannabis analytical testing

12 Mar 2020

This poster demonstrate that aqueous mobile phase preparations from purchased lab grade bottled water yielded comparable results to in-house prepared water (Sartorius Arium purified water Type 1 and Type 3) and that using filters (Sartorius Minisart® RC, SRP, NY & NY Plus, all 0.2 µm) yielded comparable results to unfiltered specimens under the same mobile phase conditions.

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

FiltrationFiltration and microfiltration are used to separate solids, particulates or large molecules from fluids (liquid or gases) in order to purify the filtrate. Explore a range of filter formats, including filter paper, plates and membranes for your separation needs. While larger particulates may be separated by gravity filtration, smaller particulates may require additional force for timely separation. Microfiltration equipment includes vacuum filters, as well as positive pressure, crossflow and centrifugal filtration devices. Find the best filtration products in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Water PurificationThere are a number of water purification methods available to remove contamination from laboratory water. These systems include demineralization, reverse osmosis, filtration and ultrafiltration. A combination of methods is sometimes necessary to achieve purified water suitable for use in experiments.Sample PreparationSample preparation can improve the quality and speed of separation techniques. Products to assist sample preparation include filtration equipment, evaporators, membranes and sieves.CannabinoidsCannabinoids are compounds found in cannabis that have therapeutic effects, such as pain relief, anti-inflammatory properties, and potential neuroprotective benefits. Research into cannabinoids is growing, particularly in the fields of pain management, neurological diseases, and cancer treatments.
