San++ Automated Wet Chemistry Analyzer - Continuous Flow Analyzer (CFA)

http://www.skalar.com/assets/flash/Continuous.swf

Overview

The San⁺⁺ Automated Wet Chemistry Analyzer also known as Continuous Flow Analyzer has been designed as a modular system to meet the needs of laboratories which process a few samples or large volumes of samples. Based on the Continuous Flow Analysis (CFA) or also called Segemented Flow Analysis (SFA) technique, up to 16 analytical measurements can be made on a single sample simultaneously. With the addition of rinsing valves and software the San⁺⁺ system can automate; start-up, shut-down, dilutions, reruns, clean-up, and raw data storage.

Skalar, the world leader in wet chemistry technology offers, over 300 proven applications utilizing various combinations of automatic dilutions, additions, mixing, heating, dialysis, extractions, distillation, digestion, phase-separation, hydrolysis, ion-exchange/reduction and more. Skalar has developed a proven systematic approach to providing a quality system starting with complete applications engineered on customer samples to provide the best possible configuration to the customer needs and requirements, training and installation by qualified specialists and complete application and service support.

Chemistry Section

The unique concept of the chemistry section has proven its performance for hundreds of applications, with maximum operator convenience and lowest routine maintenance. The latest developments in Continuous Flow Analysis (CFA) have been integrated into the chemistry modules.
The throughput of the analyzer depends upon application and can vary from 25 to 120 analyses per hour. Complex manipulations such as distillation, in-line UV digestion, extraction, etc. are incorporated on the chemistry modules.

• Robust unique double radius pump deck for accurate dosing with up to 2x 16 pump tubes.
• 2 separated pump decks for 2 x 2 channel concept.
• Controlled synchronized 10 channel air injection with separated build-in compressor for increased flow stability and fast start up.
• Easy access to chemistry modules with flexible ultra low carry-over connections between dialyzers, reactors, coils, flow cells and other components.
• Leak detection
• 3 - Cuffs long life pump tubes.
• Manual operated and automatic software controlled rinsing valves for easy automatic start up and overnight operation.

The Chemistry section is compact and easy to handle. It houses up to 5 chemistry modules with build in robust dosing pump and air injection system, up to 5 easy interchangeable modules with build in photometric detectors and 5 separated waste receptacles.

Detectors

The Skalar San⁺⁺ range of detectors comprises digital dual channel colorimetric detectors, the unique digital matrix correction detector with automatic background correction for specific sample matrixes, but also covers a range of detectors for I.R., UV, Fluorimetry, ISE, Flame Photometry, pH meter, Density meters, etc. The Skalar range of detectors covers all detectors required for the hundreds of Skalar field tested SFA applications available today.

Special features of the detectors for the San⁺⁺ Continuous Flow Analyzer (CFA) are:

• Compact design and software controllable
• Allows the implementation of bubble gating
• Easy access and no alignment of robust flow cells
• Increased stability, sensitivity and auto-scaling by digital detectors
• Automatic matrix and blank correction
• Wide linear measuring range

Software

The San⁺⁺ FlowAccess™ V3 data acquisition Windows® software package controls the complete analyzer, with auto start-up and shut down, hardware functions control, detector auto-scaling, pre-and post run sample dilutions, result calculation and statistics. 1 to 16 channels, with multiple samplers and multiple needles are handled simultaneous. Each chemistry can be grouped for analysis. As of it GUI the package is extremely users friendly and easy to operate, and will integrate easily into a network.

The FlowAccess™ V3 software package has a flexible sample table layout, with auto numbering and editing during analysis run. Sample ID.'s can also be imported from LIMS or read by the automatic bar code reader.

Flow Access has preset QC. criteria, with real time peak and result information on screen, with zooming and rescaling and real time peak editing. A
