Food and beverage testing is a critical scientific practice that ensures food safety, food quality, and compliance of food and drink products. Through comprehensive analysis, food testing labs assess factors such as microbiological contamination, chemical residues, nutritional content, and authenticity. By adhering to strict regulatory standards and industry guidelines, food and beverage testing helps maintain product integrity, fight food fraud, prevent foodborne illnesses, and meet consumer expectations for safety and transparency. Explore how food and beverage testing labs play a pivotal role in safeguarding public health and promoting trust in the global food supply chain.
As an alternative to conventional columns, PharmaFluidics offers micromachined nano-LC columns or micro Pillar Array Columns (µPAC™). These µPAC™ columns display exceptional separation properties with unprecedented peak capacity and narrow peak shapes at low operating back-pressure. µPAC™ column, 200 cm length, with pillar array backbone at interpillar distance of 2.5µm, C18.
With an internal volume of 3µL, this 50 cm long RP-C18 µPAC™ column is perfectly suited to perform high throughput analyses with shorter gradient solvent times (30, 60 and 90-minute gradients) and it can be used over a wide range of flow rates, between 100 and 2000 nL/min. µPAC™ column, 50 cm length, with pillar array backbone at interpillar distance of 2.5µm, C18.
Our µPAC™ Trapping column was developed with an identical stationary phase support morphology, matching perfectly the retentive properties of our analytical µPAC™ columns. Effectively desalting and preconcentrating the analytes improves the analytical column lifetime and workflow throughput.
Because the column is meanly made out of silicon which is semi-conductive, a dramatic impact on the chromatographic behavior of our µPAC™ columns has been observed if no appropriate precautions are taken in case the column is connected to an ESI source of a mass spectrometer. Therefore we developed a custom made grounding cable to shunt the high voltage to ground.
The µPAC™ capLC columns are designed for increased robustness and throughput assuring sensitivity. A flow rate versatility between 1 and 15 µL/min at moderated pressures allows short gradient separations, while the µPAC™ technology ensures an exceptional high reproducibility over time and across laboratories. µPAC™ column, 50cm length, with pillar array backbone at interpillar distance of 2.5 µm, C18.
The µPAC™ Flex iON Connect is a user-friendly interface to facilitate fast, reproducible and low dispersion connection of µPAC ™ nanoLC columns to Thermo Fisher Scientific Nanospray Flex™ Series ion sources. It is compatible with any type of 360µm OD electrospray emitters through one-piece fingertight fitting and it embeds a preassembled liquid junction configuration to achieve the best performance.
