The Sanseries of Automated Wet Chemistry Analyzers also known as Continuous Flow Analyzers have been designed as modular systems 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 (depending on the model) can be made on a single sample simultaneously. With the addition of rinsing valves and software the Sanseries of analyzers can automate; start-up, shut-down, dilutions, re-runs, 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 provide 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 32 or 16 pump tubes (San++
  • 2 separated pump decks for 2 x 2 channel concept (San++)
  • Single pump deck wit 21 pump tube positions (Sancompact)
  • 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 built-in photometric detectors and up to 5 separated waste receptacles (depending on the Sanseries model).


Detectors_thumbThe Skalar Sanseries 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 series Continuous Flow Analyzers (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


The Sanseries 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.

Some features highlights:

Table wizard
The “Table wizard” tool can be used to create easily and quickly a complete sample workload table with a standard layout. The table’s structure and fields can be customized by stepping through the wizard. Values for the drift/wash, calibration standards and CLP intervals for the samples can be defined. By adding the total number of samples the final analysis table is automatically made. The sample table will be displayed and for each type of sample an editable field for user comments is available if required. The table can be exported to an ASCII/Excel file. Sample workloads can also be imported from a LIMS file or ASCII/Excel.

FlowAccess™ V3 includes the function of automatic preparation of pre- and post dilutions with enhanced settings. The pre- and post dilutions factors can be defined by the user per chemistry parameters. Advanced settings for automatic post-dilutions are available like series of post-dilutions where the user can define the maximum number of times a diluted sample has to be re-diluted and re-analyzed.

Real time
During the run, all the analysis peaks can be viewed, each channel separately in detail or multiple channels simultaneously, maximum of 16, in one single screen view. Peak marking, sample ID and calculated results are displayed in real time. Advanced peak diagnostics is available. Real time results are calculated by 1st, 2nd order calibration curve according to ISO 8466 or 3rd order and inverse logarithm for use with Ion Selective Electrodes.

Contract Laboratory Program (CLP)
The software complies with CLP protocols ensuring accuracy and precision of analytical results. The CLP protocol allows automatic actions by the San++ system if QC and CLP limits are exceeded. These QC and CLP limits are user definable and have to be set for each parameter individually. Generally the following CLP samples are defined like initial Calibration Verification (ICV), Continuing Calibration Verification (CCV), Laboratory Control Sample (LCS), Spike Recovery (SR) etc.. When a CLP sample is calculated to be outside the set limits, the analyzer executes the required action. It is possible to define up to four actions, which are for example for ICV: Re-run ICV, Re-run Standards, Abort run and show messages and Continue run and flag results.

Optional add-on software programs:


FlowReport™ is a powerful reporting tool to generate customized reports from the results obtained in FlowAccess™. These reports allow customized set up with different configurations for data and graphics. The software enables reports to be generated quickly and easily. The design possibilities are extensive. A report consists of four parts: Methods, Results, Real Time and Calibration Curve, which have to be set up separately. All parts of the custom made report can be viewed, printed and exported to an ASCII/Excel file or in a picture format.
