Water / Wastewater Australian Institute of Marine Science Chooses Matrix Gemini LIMS


The Australian Institute of Marine Science (AIMS) has chosen the Matrix Gemini Laboratory Information Management System (LIMS) from Autoscribe Informatics to monitor workflow across its three operations sites. AIMS has a unique set of laboratories to support various marine research activities, with sites in Townsville, Perth and Darwin. The Townsville headquarters is home to 10 laboratories specialising in advanced analytical chemistry, biomolecular analysis, biology, chromatography and symbionts culture.


Large quantities of samples for laboratory analysis are collected regularly during field trips. The expansion of AIMS science activities and the increased demand on the laboratories prompted the need for a LIMS. The Matrix Gemini LIMS was chosen following a comprehensive selection process which included on-site and online demonstrations, site visits and detailed discussions of the required functional specification.


Dr. Muhsen Aljada, Institute Laboratory Manager at AIMS, said: “A critical requirement of the LIMS is the ability to be integrated with the laboratories across our three operation sites and to manage both incoming and outgoing samples. We have samples submitted internally (within our three operations sites) and samples submitted to us by external clients or collaborators. AIMS also outsources some analysis to external laboratories so we also need to manage these samples and their incoming results.”


“Matrix Gemini fulfills these requirements,” he continued. “In addition, it is easy to use and the configuration tools mean that it will be straightforward to make any changes in the future, without writing specialised programming code, if and when our requirements or workflows evolve. The LIMS went live in July 2017.”


John Boother, President of Autoscribe Informatics commented: “The successful implementation of Matrix Gemini at AIMS reinforces the flexibility and versatility of the system. For multi-site systems Matrix offers the flexibility to be configured to meet the specific work process at each individual site. This means that users are not constrained to a centralised system that might not be set up in the way they would like. In addition, Matrix Gemini’s dual web/Windows user interface means that system access is available from any location that has web connectivity, either on a PC or mobile device such as a tablet.”


An Accurate and Low Maintenance pH Measurement System is

Developed REFEX and Northern Ireland Water (NIW) together developed an accurate and low maintenance pH measurement and control system for optimising coagulation in cold, low ionic raw water feeding into the 23 Water Treatment Plants operated by NIW and Kelda (Yorkshire Water) in Northern Ireland.

After six months of evaluation, it was determined that REFEX sensors paired with either Knick or Yokogawa pH transmitters provided the best performance overall. It is important to note that both the Knick and Yokogawa transmitters have galvanically separated dual high impedance inputs (2 x 1012Ω) for their pH and reference connections. This high impedance characteristic protects the electrodes well from potentially damaging ground loops and noise.


The NIW/Kelda engineers that carried out this project were Alan Jackson (now retired) and Roy McAlonon (now telemetry). Both Alan and Roy have recommended and approved REFEX pH sensors with Knick or Yokogawa transmitters for use in the WTW’s in Northern Ireland and have provided testimonials endorsing these 2 pH arrangements and their performance.


As a result of the testing, REFEX/Knick combination was chosen by NIW/Kelda water as their corporate standard for measuring pH. The RFEEX/Knick arrangement was found to provide the best accuracy, the fastest response to pH change and had the lowest maintenance cost.


REFEX sensors are deployed in a variety of applications throughout the system: Incoming raw water pH measurement for correction/coagulation optimisation, Primary filter pH measurement, Secondary filter pH measurement, Manganese filter pH measurement, Final water pH measurement and correction.


Savings in excess of £1.0MM in total have resulted from standardising on the REFEX/ Knick pH arrangement at NIW/Kelda Water.


Using the REFEX solution, it was clear that the quality of water received by each WTW was significantly improved. The ability to continuously optimise coagulation in the raw water had significant benefit for downstream filtration. Overall, treatment and production efficiency was increased with an improvement in consistency of final water quality while driving down direct costs.
