- Compliance with Reference Methods.
The NexaFlo™ stands out as a premier Segmented Flow Analyzer (SFA), a specialized subset of Continuous Flow Analysis (CFA) techniques. SFA, with its distinctive method of segmenting the sample and reagents by air bubbles, falls under the broader CFA umbrella, combining the efficiency of continuous flow with enhanced precision and reduced cross-contamination. This unique approach enables the NexaFlo™ to conduct a wide array of analytical procedures effectively.
Designed to accommodate both micro-bore and macro-bore SFA methods, the NexaFlo™ allows for the execution of complex analyses ranging from straightforward colorimetric tests to intricate in-line distillations and digestions. The integration with an autosampler is essential for the management of sample intake, complemented by various sample preparation systems tailored to the selected analysis method. This comprehensive control and operation are facilitated through the NexaFlo™ software, potentially enhanced by the optional Auto Module.
Through this automation, NexaFlo™ is particularly adept at handling the most complex sample preparation and operational tasks. Techniques such as dialysis, distillation, UV digestion, injection, dilution, mixing, incubation, and liquid/liquid extraction are performed with unparalleled efficiency. All processes, including system start-up and shutdown, standard solution preparation, sample concentration adjustments, and automatic cleaning protocols, are fully automated, ensuring high throughput and precision in every analysis.
Each NexaFlo™ integrates a high-precision 3-speed peristaltic pump (medium, fast for startup and washout, and slow for low reagent consumption), an analytical manifold, a unique reagent containment drawer, and a UV-Vis Colorimeter detector (Flame Photometer and Fluorimeter available are options). Additionally, the NexaFlo™ 450 features an integrated color touchscreen display, whereas for other NexaFlo™ models, the software displays through an external PC.
The NexaFlo™ analytical software is dedicated to Segmented Flow Analysis, a subsegment of Continuous Flow Analysis (CFA) technology. It prepares calibration standards, runs samples and quality controls, dilutes any out-of-range samples, prints reports and QC charts, exports data to LIMS, washes out the manifold and manages shutdown operations.
The software is user-friendly, efficient, and powerful, designed to simplify day-to-day operations. It runs the analysis of all parameters on each channel (up to 14 channels) and drives auto-samplers and accessories for automatic sample preparation. A simplified version of the NexaFlo™ software is run on NexaFlo™ 450 with a color touchscreen display for easier diagnostics, maintenance, device setup, significantly improving the user experience.
During analysis, the software monitors all performance details (heating bath temperature, voltages, detector outputs) and alerts the user of any problems.
