What is the AMPTS

AMPTS is the analytical tool preferred by scientists and engineers for conducting anaerobic batch fermentation tests. The latest generation of AMPTS comes in two models (AMPTS III and AMPTS III Light) that house 18 or 9 test vials, respectively. AMPTS III automates and simplifies a wide range of testing, including biochemical methane potential (BMP) tests, biogas potential, anaerobic biodegradability studies, specific methanogenic activity (SMA) assays, and residual gas potential (RGP) analyses on digested slurry. With either AMPTS III model, sampling, analysis, recording and report generation are fully integrated to offer users a seamless testing experience.

Determine the true biogas and methane potential

AMPTS allows you to determine the true biogas and methane potential as well as dynamic degradation profile of any biomass substrate. That means you can more easily determine the optimal retention time and mix of substrates for co-digesting, screen proper pre-treatment methods, evaluate the need for additives, and even assess the biological performance of an individual biogas digestor or process configuration.

Reduce labour and skill demands

AMPTS significantly reduces labour demands and risk of human errors when compared to traditional methods or competitive solutions on the market. After a few hours of experiment preparation and setup, the run process is fully automated by AMPTS until the test is over. Experimental data can be easily reviewed in real-time or from a downloaded report at any time, making testing easier than ever before.

Embedded solution with no need for external computer

AMPTS features inbuilt storage and processing from an onboard embedded microcontroller, which allows the tool to store all gas volume and flow measurements locally. This eliminates the need for an external computer, so you no longer need to worry about losing data due to a computer crash or automatic operational system upgrade that could cost you weeks of research and development work. The large storage capacity of 15 million data points allows for collection of up to 130 000 liters of gas per experiment.

Robust operations with modular design

AMPTS is designed and manufactured in Sweden, adding the best elements of Scandinavian form and function to quality and reliability. AMPTS ensures no data is lost, even if the entire system goes down. The modular design makes the maintenance of AMPTS easy because many parts can be exchanged without sending the instrument to a workshop. 

Standardise and compare results

AMPTS is a universal platform for all anaerobic batch fermentation tests, allowing for the standardisation of measurement procedures, data interpretation and reports. With the real-time temperature and pressure compensation, the measured biomethane volume and flow are normalised under standard condition (i.e., 0 °C, 1 atm and zero moisture) and the measurement interference caused by variations of external measurement conditions can be minimised. This allows for data from different laboratories around the world to be easily compared, thus creating value over and above the high-quality results delivered by AMPTS.

Strong and reliable agitation

Driven by high-quality brushless step motors, the agitation system included with AMPTS effectively delivers gentle, precise, and reliable agitation in a gas tight environment. Its ability to work well even in the harsh environment of anaerobic fermentation is why so many satisfied customers around the world rely on AMPTS as their preferred device for anaerobic bath fermentation testing.

Measure total biogas and estimate gas composition in real time

With its gas tight enclosed measurement chambers, the new AMPTS III is able to measure total biogas with minimal losses of carbon dioxide. In addition, by connecting two measurement chambers in a series before and after removing carbon dioxide, it is possible to estimate the gas composition in real time.

Application areas

The AMPTS  can be used for a large number of anaerobic bath tests. Examples of these are:

  • Biochemical methane potential (BMP)
  • Biogas potential
  • Specific methane activity (SMA)
  • Residual gas potential (RGP)
  • Biochemical hydrogen potential (BHP)

AURORA™ Software, pre-installed on AMPTS III

Bring your experiment to life with Aurora™ software

Aurora™ is BPC Instruments’ latest and revolutionary software solution for monitoring anaerobic batch fermentation tests. Its slimmed down design makes it optimal for users to set up an experiment, monitor its progress and download results with little effort. Aurora is included and comes pre-
installed on AMPTS without the need for software licences or installation on external computer.

Results from anywhere on any device

AMPTS is designed to allow easy access from a remote location using any device with a web browser. Monitor your experiment from your office and home with your computer, tablet or phone of choice. You can also expand the analytical capacity of AMPTS easily by connecting multiple instruments together with an Ethernet switch. With this feature, each AMPTS can be operated as a stand-alone device or connected in parallel, depending on your needs.

What people say?

The AMPTS systems are more than just data generators; they are reliable tools that have significantly contributed to our research. The user-friendly operation and high level of automation make them stand out among the methods we use for BMP determination in our lab, which include mainly manual methods. Their reliability is unmatched, making them the most popular choice for our research.

…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.
