Clean bore ultrasonic fl ow meters for laboratory applications


Are you trying to set up your lab for PFAS analysis?


Per- and polyfl uoroalkyl substances (PFAS) are a large family of over 4,000 synthetic chemicals that have been widely used in industry and consumer products. Due to their carbon-fl uorine bonds, PFAS resist degradation and elevated temperatures. However, their characteristic stability means that PFAS can also persist and accumulate in the environment, which poses certain risks to animal and human health. For this reason, several PFAS are subject to regulations restricting their use and their concentrations in various matrices.


Understanding PFAS analytical methods and regulations as well as choosing the right instruments and consumables is key to getting your lab ready for PFAS analysis. To shorten startup time, Agilent provides LC/MS/MS eMethods to get you up and running in the shortest time possible.


Titan Enterprises manufacture clean-bore, low-fl ow, fl ow sensor solutions for laboratory tests and pilot plant applications.


Titan’s rugged, clean bore construction of their Atrato® ultrasonic fl ow meter range is ideal for a wide range of low-fl ow laboratory applications – with the additional benefi t of being very easy to clean between experiments.


The Atrato ultrasonic fl ow meters use patented ‘time-of- fl ight’ ultrasonic technology that enable them to operate with unmatched accuracy over a wide fl ow range, from 2ml/min to 20l/min.


The Atrato’s advanced signal processing system permits fl ow measurement across the whole Reynolds number range allowing both viscous and non-viscous fl uids to be metered accurately. The superior construction and electronics, coupled with Titan’s unique algorithms, remove the need for zero-point adjustments.


Powerful, yet very easy to use, Atrato fl ow meter software enables data recording via an external computer. With features that provide monitoring, reporting and management of liquid fl ow data, the software delivers a continuous picture of tests or experiments and offers a reliable alternative to restrictive and costly manual metering.


Users can select from a wide variety of functions and time periods over which to store results. Flow data sets are saved as .csv fi les which can then be imported directly into software packages for later manipulation and analysis.


fl ow meter provides an easy-to-clean system with no moving parts, virtually eliminating mechanical wear, critical for long-life and repeatability.

The PFAS in Drinking and Surface Water by LC/TQ eMethod is verifi ed for the separation and reliable detection of 100 native and isotopically labeled PFAS in drinking and wastewaters, including 60 PFAS with reported method detection limits. The method includes target compounds that are part of standard methods and regulatory lists such as EPA Method 537.1, EPA Method 533, SW-846 Method 8327, SW-846 Draft Method 8327, ASTM D7979-19, ASTM 7968-17a, ISO 21675:2019, Europe (EU) WfD & DWD, Japan Drinking Water Quality Standards, and Germany DIN methods. The Agilent 1290 Infi nity II LC and the Agilent 6470 triple quadrupole LC/MS are used in combination to provide high-quality LC/MS/MS results. Sample preparation is performed with Agilent SampliQ weak anion exchange (WAX) cartridges, and an Agilent ZORBAX RRHD Eclipse Plus C18 column is used in LC analysis.


In addition to acquisition and quantitation methods, the PFAS eMethod includes sample preparation protocols, a detailed training video with a step-by-step workfl ow guide, and references to expertly selected consumables and supplies to minimize cost and effort to design and plan the required analyses.


The eMethod makes use of the Agilent PFAS multiple reaction monitoring (MRM) database for triple quadrupole LC/MS, which features data for over 100 native and isotopically labeled PFAS. The database includes details of the intrinsic properties and identifi ers of PFAS such as chemical name, CAS number, and molecular formula. It also features optimized MRM parameters for the analysis of 72 native and 36 isotopically labeled compound from 14 PFAS groups, as well as retention time data from optimized methods.


The eMethod is designed for labs that want a widely applicable testing method and that do not plan to run dedicated regulated methods. For labs running regulated methods, the eMethod in conjunction with the Agilent PFAS MRM database can be a helpful building block to modify existing methods to expand analytical capabilities.

In-line sample preparation (ILSP) uses the power of an LC-MS/MS to streamline and automate sample extract clean-up. Restek’s Revive ILSP Pesticides cartridges are an ideal sample preparation alternative for food safety labs seeking to spend less time and money on multiresidue pesticides samples without sacrifi cing performance. Revive ILSP Pesticides cartridges separate analytes from potentially interfering matrix components just like conventional QuEChERS and SPE methods do, but they replace time-consuming manual procedures with a faster automated clean-up process that occurs on the instrument concurrently with sample analysis.

With a Revive ILSP Pesticides cartridge, six-port valve, and an independent isocratic pump, your instrument can be transformed into an analytical workhorse, combining sample clean- up and analysis in a single, effi cient method. Signifi cantly decrease sample preparation time, cut the costs associated with disposable sample prep products, and reduce errors related to manual procedures by integrating Revive ILSP into your current methods for multiresidue pesticides analysis in foods.
