Analytical tool for feedstock quality control

AMPTS® II Light

- reliable tool for feedstock optimisation in anaerobic digestion

AMPTS® II Light is developed for biogas plant operators to quickly evaluate biomethane potential or biogas potential from various biomass substrates. It lets operators fully explore the energy potential of all available substrates and make better business decisions based upon the true value of a substrate.

Use AMPTS® II Light to discover biochemical methane potential (BMP), residual gas potential (RGP), anaerobic biodegradability and specific methanogenic activity (SMA) assays for a small number of samples.

Biogas potential test equipment for biogas plants

AMPTS® II Light enables:

  • Precise and accurate data
  • Significant reduction in time, labour and skill demands
  • Standardising measurement procedures, data interpretation and reports
  • Remote access and user-friendly operations
Biogas and methane gas measuring instrument

Transforming substrates into profit

Better monitoring of changes in substrate energy content significantly reduces time, labour and skill demands, making your operations more accurate and profitable. AMPTS® II Light provides reliable data from experiments carried out under different conditions.

Standardised measurement

The real-time temperature and pressure compensation feature minimises and standardises the impact of measurement conditions. The temperature and pressure of the gas are measured every time a flow cell opens, allowing you to derive exact kinetic information compensated for any variation of ambient temperature and pressure over time while considering the vapour content of the gas.

Software for online data monitoring

Monitor from your smartphone or tablet

AMPTS® II Light allows easy access from a remote location using any computer, smartphone or tablet. It uses standard protocols and connections secured by a user-definable password, behaving like any other unit on an internal network.

Connect multiple instruments using a network switch for analytical capacity expansion or use AMPTS® II Light as a stand-alone device depending on your needs.

Stable, reliable operation

AMPTS® II Light software offers unmatched stability, data protection and minimum downtime as it runs on an embedded ARM CPU using the Linux operating system.

Incubator with 6 reactors

Analysis made easy

Easy to understand and navigate, you can set up an experiment, monitor its progress and download the results with little effort. All data is in a format that allows for easy analysis.

The software also automatically calculates and generates experiment guidelines for the amount of substrate and inoculum needed in each batch test.

Laboratory instrument for feedstock optimisation

Standardise and compare results from any lab – anywhere

AMPTS® II Light gives easy, instant access to ongoing experiments and reports to professionals all over the world, saving lots of time and effort. It allows you to standardise measurement procedures, data interpretation and reports, and normalise data (i.e., 0 ˚C, 1 atm and dry conditions).

Automatically removes gas overestimation

Methane gas overestimation arises from flushing the system with an inert gas such as nitrogen. Biogas produced from the anaerobic fermentation will push the remaining inert gas out from the reactor headspace and the inert gas can mistakenly be counted as methane gas. This means a possible overestimation of methane gas production by as much as 20–30 percent depending upon the total volume of gas production and headspace volume of the test vial. AMPTS® II Light calculates and removes this overestimation, providing for more accurate and reliable data.

Customer reviews

What people say

…it saves time by enabling quick and automatic batch experiments with very little manual labour, and that it is “student proof”, because the instrument does not require long experience or training before you start using it.

MR. AURELIEN PERRAULT
Project Manager, Sludge & Energy Innovation, Thames Water, UK

AMPTS helped us minimising the differences in laboratory skills between different researchers by following the same procedure for BMP testing in which manual handling is minimised, while a huge number of data points are gathered… By using AMPTS apparatus we can achieve reproducible results even with students who perform the test for the first time. We now include the AMPTS as a standardised test in our regular curriculum practical work.

PROF. JULES VAN LIER
Delft University of Technology, the Netherlands

…the automation of the test minimises human errors, makes data collection more frequent than manual methods, and reduces operator time allowing more time for performing alternate tasks.

ASSOCIATE PROF. BERNADETTE MCCABE
University of Southern Queensland, Australia

…the AMPTS II is the key piece of equipment for Digester Doc, as this equipment is used in determining current and potential energy values as well as in other troubleshooting activities. Digester Doc’s clients get help to identify the most suitable bacterial or mineral innoculants and feedstocks wisely, and potentially get at least 25% additional energy values out of their facilities. One of our many success stories is New Energy One, LLC in Idaho, where they were able to double production in just three months due to the AMPTS II usage.

MR. WILL CHARLTON
President, Digester Doc, USA

…the AMPTS II significantly reduces labour demands and enables our students to more efficiently utilize time during class. The setup of the AMPTS II system is easy to follow and it’s a powerful tool for demonstrating and teaching anaerobic digestion processes in both undergraduate and postgraduate courses.

DR. XUNDONG LIU
Tsinghua-SUEZ Environnement Environmental Science and Engineering Experiment and Practice Educational Laboratory, China

We use AMPTS II for both sales process and technical process optimization. The biomethane potential test performed with AMPTS II can provide useful data to demonstrate benefits of Cambi thermal hydrolysis technology for sludge pre-treatment before anaerobic digestion. This allows our clients to evaluate the possible return of investment on implementation of Cambi thermal hydrolysis treatment in wastewater treatment plants.

MR. STEFAN SANDBACKA
Vice President of Business Development at Cambi Group

During my studies, I earned some money for reading-off the eudiometer, as BMP tests were conducted by simple apparatus with high human-resource allocation. Investing in an AMPTS II system is indeed a substantial cost factor in the beginning, but it will easy pay-off when considering the savings in manpower and the higher quality and resolution of the obtained data. I can strongly recommend the AMPTS II to everybody interested in a reliable workhorse.

DR.-ING. KONRAD KOCH
Department of Civil, Geo and Environmental Engineering, Technical University of Munich, Germany

University of Applied Sciences (The Netherlands), actually I have a presentation at the EUBCE in Stockholm where I will be presenting the talking about balancing the supply & demand of renewable Energy. Our AMPTS II has played a big part in providing us with a lot of reliable data…
