Continuous on-line reproducibility of 5 ppt which enhances our ultra-high measuring range of silica trace levels in ultra-pure water


Hinwil, Switzerland 17-08-2016 – SWAN’s AMI Silitrace Ultra is a unique product solution that embodies continuous reproducibility with ultra-high accuracy in the on-line monitoring of silica concentration in ultra-pure water (UPW), to ensure the integrity of product quality.


  • Measuring range: 5 ppt (0,005 ppb) to 25 ppb
  • Reproducibility: ± 0.005 ppb or ± 5%
  • Continuous and automatic monitoring of main instrument functions such as: sample flow, reagent supply and process integrity
  • UPW concentrator (patented “Carrcentrator” or Reversed Osmosis System created by SWAN AG in partnership with Intel Corporation)

The AMI Silitrace Ultra is the only product of its kind, capable of combining a measuring range of 0.005 ppb - 25 ppb, previously only obtainable through sample testing in analytical laboratories, with an on-line and continuous reproducibility of ± 5 ppt. Knowing true contaminant levels at all times is crucial for gap free data accumulation and valuable (future) trend analyses.
This is due to the fact that the AMI Silitrace Ultra uses the UPW concentrator technique; an evidence based method that enhances our powerful on-line silica analyzer to continuously monitor real silica levels in UPW up to 40 times more accurate. This technique uses the innovative UPW concentrator (Carrcentrator), which was created by SWAN AG in partnership with and patented by Intel Corporation.

Greetings from the team at SWAN ANALYTICAL USA

SWAN Analytical USA is a leading manufacturer of high quality on-line analytical instruments for water analysis in applications such as high purtiy water, steam, condensate, cooling water, potable water and effluent. SWAN instruments measure a number of parameters within these applications such as turbidity, chlorine, sodium, dissolved oxygen, pH, ORP and others. Built with Swiss precision, SWAN's reliable analyzers are designed with the operator in mind.

New SWAN Distribution Quality Monitors – Multiple Parameters; One Simple Panel

The SWAN DIST series Distribution Quality Monitor line offers three options for measuring chlorine, pH, conductivity and turbidity on one easy to install, easy to maintain panel. Versatile output options ensure water quality throughout your distribution system, proving piece of mind and customer satisfaction.

Three models are available for continuous monitoring of critical parameters for early warning at wells, pump stations and throughout the distribution system.
  • SWAN Dist 1 features reagentless free chlorine measurement.
  • SWAN Dist 2 provides colorimetric, DPD based free chlorine measurement.
  • SWAN Dist 3 provides colorimetric, DPD based free and total chlorine measurement.
All three include pH and conductivity sensors in an easily accessible and easy to service flow cell. They also feature SWAN's non-contact Turbiwell turbidity monitoring.

Complete system comes pre-mounted on panel, ready for operation. Simple 4-20 outputs for each parameter used with SCADA provide an in depth record of water quality. Built in surveillance functions generate alarms if measurement is not valid, such as missing flow, empty reagents, valve and photometer functionality.

Product News (December 2015)

Our most established member of our Silica Family is AMI Silica, which was introduced in 2011 and remains the ideal instrument for boiler water and steam application for values higher than 1,0ppb.

Our Silica family has been complemented with two new analysers, AMI Silitrace and AMI Silitrace Ultra. AMI Silitrace, one of the newest members, is suggested to be used in low temperature applications as the reaction chamber is temperature controlled, which leads to reliable measurements under these conditions. In comparison to the AMI Silica we were able to enhance the measuring range from 0,5ppb to 1'000ppb.

AMI Silitrace Ultra
, the other new member, is our on-line monitor for reactive silica in the lowest range. Our AMI Silitrace Ultra is the only instrument on the market, which is able to measure ultra-low silica concentration levels to fulfil the strict limits of the new guideline of the International Technology Roadmap for Semiconductors (0,005ppb to 25ppb).

SWAN Launches New Monitor AMI CACE

Acid conductivity monitoring - No more resin changing required

Hinwil, Switzerland 04-10-2016 – SWAN has re-invented the conductivity measurement with an attractive blend of reproducibility and performance, lowering resin consumption and significantly minimizing time and costs spent on maintenance.
AMI CACE continuously measures conductivity, before and after cation exchange, as well as determining the pH value of the sample and alkalizing reagent concentration.
The online monitor AMI CACE will be a key component of current and next generation water steam cycle instrumentation as it enables significant cost savings at increased instrument availability.

  • No resin changing or resin rinse down time required
  • Low maintenance
  • Continuous monitoring of sample flow and sample temperature
  • Short response time for the detection of anions

SWAN proudly announces its newest product development: Handheld CHEMATEST 30

Chematest 30 ink, Koffer.jpg

With the introduction of CHEMATEST 30 SWAN broadens its range of applications for handheld water quality testing devices. In addition to potable water treatments and public pools, these successor models to the well-proven CHEMATEST 20/25 photometers are now qualified for use in pharmaceutical production and food processing.

Primary improvements affect the area of application and user-friendliness. In order to comply with pharmaceutical and food industry requirements, every photometer is calibrated individually and its light source traceable to NIST standards. Traceable verification kits and glass cuvettes additionally assure reliable and safe utilization. 

Its menu-driven user guidance has been revised to simplify measurement handling. The IP 67 waterproof design, its long-living, rechargeable Li-Ion battery and the large internal data storage make CHEMATEST 30 the perfect handheld for mobile water analysis in any circumstances. 

Disinfectant measurements:  

  • Free, Combined and Total Chlorine
  • Ozone
  • Bromine
  • Iodine
  • Chlorine Dioxide


Additional photometric methods:

  • pH (Phenol Red)
  • Cyanuric Acid


More newly introduced CHEMATEST 30 highlights:

  • User Management
  • Registration of Sampling Points
  • Bluetooth 4.0 Low Energy
  • Improved Case with Removable Reagent Rack


The CHEMATEST 30 is availabe now!
