42 University Strengthens Research Lab with Discrete Analyser


Lake Superior State University recently purchased a Seal AQ1 discrete analyser for its Environmental Analysis Laboratory (EAL). This advanced instrument was purchased to analyse local, regional and national water quality samples. However, it also fulfils an important role providing the University’s students with practical experience; working with an analyser that is employed in laboratories around the world.


The AQ1 enables students to gain hands-on experience with automated nutrient testing for many common environmental parameters with detection limits in parts per billion. Performing automated colorimetric tests on multiple samples in discrete reaction vessels, the AQ1 is ideal for laboratories with moderate workloads requiring varied tests on different samples, and for those that need fast individual results. The instrument is supplied with standard methods to USEPA, ASTM, ISO and other internationally recognised standards for the analysis of a wide variety of parameters including alkalinity, ammonia, chloride, cyanides, nitrate/nitrite, nitrite, phenolics, ortho phosphate, total phosphorus, silicate, sulphate and total Kjeldahl nitrogen.


With unattended operation including the ability to run overnight, the AQ1 has all the advantages of discrete analysis – automatic standard preparation, automatic dilution, automatic method changeover, and low reagent consumption. Interchangeable 60 or 78 position sample trays improve flexibility and with easy-to-use software, users are able to schedule tests (up to 60 per hour) and specify QC types, limits and corrective actions following a QC failure. It is also possible to add further samples after a test run has begun. Highly accurate analysis is achieved with 100% optical glass no-flow cuvettes and the maximum consumption of combined reagents and sample is 500 – 600 µL per test.


Reaction times are user programmable from seconds to minutes and all methods have been optimised to ensure that the chemical reaction is brought to full completion and steady state, which maximises sensitivity and emulates both the Manual and the Segmented Flow Methods. Once the absorbance is read, the cuvette is thoroughly cleaned, eliminating any carryover or cross-contamination.


During the summer of 2013 the lab supported twelve student-faculty research projects including Professor Derek Wright’s monitoring of the Ashmun Creek and Munuscong watersheds, and Laboratory Manager Ben Southwell’s work to characterise waters at risk from harmful cyanobacteria blooms. The lab also conducts contract work for public and private clients and offers paid internships to students that are looking for experience in a state-of-the-art lab; in 2013 eight students were employed as technicians.


“We are delighted that our analyser has been chosen by this prestigious laboratory,” said Lalicia Potter, Seal’s Technical Sales & Support Director. “Not only is the instrument making a major contribution to the lab’s ongoing environmental analysis workload, but it is also contributing to the education and experience of tomorrow’s scientists.”

New Lab Instrument Data Integration Software Released


Customers to Benefit from New Applications Support for Europe


Avacta Analytical has established a dedicated European applications support team, enabling customers to harness the Company’s expertise in protein characterisation, analysis and product formulation. This new service will help to exploit the unique capabilities of the Optim® micro volume protein analysis and characterisation instrument to its full potential, providing unrivalled customer support for a wide range of applications.


After the successful release of its IRIS software in the United States in March 2012, PAC has recently launched advanced instrument data integration software designed specifically for PAC laboratory instruments globally. IRIS Software provides customers the advantage of connecting their PAC laboratory instruments, locally or worldwide, and managing these instruments, including gathering and analysing test data, as well as communicating results, from a single computer.


This greatly improves laboratory efficiency since the software has the same look and feel across all instruments, which reduces the amount of training needed when working with multiple software platforms. In addition, it can perform data reprocessing without rerunning a sample, which increases laboratory productivity.


IRIS Software is also compliant with security and quality protocols. It includes password protection at multiple levels and user traceability. This helps ensure that your laboratory instrument data is secure and only accessible to authorised people within your organisation. Integrated statistical process control charting is also available for many instrument models.


PAC IRIS Software has numerous plugins (PAC instruments it connects to) including the Herzog OptiDist, ISL PMD 110, Herzog HVM472, ISL VIDA, and many more. All IRIS plugins include a results section to view previously completed tests, a run control section that displays real-time instrument data, a reports section to print reports, a LIMS connection to automatically transfer data, and an online manager to allow web-based control of the software and remote data access.


Some plugins have more advanced features including the ability to start a test, to define upper and lower limits and targets, to define the test results from a sample test as a standard to compare to other test results, or for users to modify units of the instrument parameters.

Optim users across Europe now have the opportunity to work with a customer-focused applications team with exceptional knowledge of the Optim technology and broad practical expertise in developing cutting- edge applications for the instrument. The highly experienced team is perfectly positioned to provide technical information and demonstrations, introductory and in depth training – either on site or via webinars – as well as method development and application support. Customers can also choose from an array of instrument service options, tailored to individual needs.


Daniel Lund, Product Manager at Avacta Analytical, commented: “With extensive hands-on experience of using the Optim instrument to perform the same types of analyses as its customers, Avacta’s newly-established European applications support team is ideally placed to provide customers with a personal service and the support they need to ensure excellent experimental results are reliably and consistently achieved.”
