Measure low gas volume and flow with high accuracy and precision

Measure low gas volume and flow with high accuracy and precision

The Gas Endeavour allows users to measure low gas volume and flow whenever there is a demand for highly accurate and precise measurements. It is an efficient analytical instrument for conducting real-time assays where gas is produced or consumed, having sampling, analysis, recording, and report generation fully integrated and automated. Its flexible design allows for gas consumption measurements as well, as well as the determination of gas composition.

Significantly reduce your labour demands

Significantly reduce your labour demands

The Gas Endeavour is a well-engineered analytical device, developed specifically for on-line measurements of low gas flows from any gas-displacing process at laboratory scale. It is simple to use and easy to learn.

This automated analytical procedure significantly reduces labour demands when compared to many traditional methods or competitive solutions on the market.

Standardise and compare results

Standardise and compare results

The Gas Endeavour is a fully automatic analytical platform designed for the real-time monitoring of biological or non-biological batch processes generating or consuming low flows of either inert or slightly aggressive gases.

The instrument provides for the standardisation of measurement procedures, data interpretation and reporting. This allows for data from different laboratories around the world to be easily compared, thus creating value above and beyond the high-quality results obtained from operating the Gas Endeavour.

Get access to high quality data

Get access to high quality data

The real-time performance and outstanding features of the Gas Endeavour satisfy the highest demands for data accuracy and precision. This high-quality data can be used to extract important kinetic information, which in turn provides for a much better understanding of your process.

Let multiple units works together

Let multiple units works together

The analytical capacity of the Gas Endeavour can easily be expanded by connecting multiple instruments with a network switch. With this configuration, each Gas Endeavour becomes a modularised device. The connected instruments are easily controlled through a single web browser interface, and can be accessed with a computer, tablet, or smartphone. In this way, each Gas Endeavour can be operated as an individual instrument or connected in parallel to increase the analytical capacity, entirely dependent on the user needs.

Modular design for easy upgrade and maintenance

Modular design for easy upgrade and maintenance

The Gas Endeavour has a modular design with standardised flow cell chambers, and other key components. This allows for a flexible system set-up, easy upgrading options and simple maintenance.

Each test line of the instrument is equipped with an individual flow cell chamber with the desired measurement resolution, depending on the user needs.

Outstanding real-time performance

Outstanding real-time performance

The Gas Endeavour is an efficient analytical instrument for conducting real-time assays in which gas is produced, having sampling, analysis, recording, and report generation fully integrated and automated. Its design allows for gas consumption measurements as well, as well as the determination of gas composition.

The multi-channel analyser consisting of 15 parallel test vessels and the same number of gas flow meters attached to an embedded data acquisition system and web-based software user interface, allows for the real-time investigation of a high number of samples. This unique design makes the Gas Endeavour an extremely precise and accurate instrument, with a wide range of applications.

Temperature and pressure compensation

Temperature and pressure compensation

The real-time temperature and pressure compensation feature of the Gas Endeavour ensures that the impact of measurement conditions can be minimised and data presentation is standardised.

The temperature and pressure are measured every time a flow cell opens, allowing the user to derive exact kinetic information compensated for any variation in ambient temperature and pressure over time, while considering the vapour content of the gas as well. The normalised volumes are presented under dry conditions at 0 oC and 1 atm.

Optional removal of gas over- or underestimation

Optional removal of gas over- or underestimation

The Gas Endeavour can be used to measure both total gas and/or the remaining gas after absorption of a part of the gas. For example, methane production can be measured when carbon dioxide is removed from the gas. When certain gases are absorbed and only a remaining gas is measured, an over- or underestimation of the gas production arises when the composition of the produced gas differs from the composition of the head space gas at the beginning of the test. The Gas Endeavour can calculate and remove this over- or underestimation, providing for more accurate and reliable data on the measurements of gas production.

Network ready and easy access

Network ready and easy access

The Gas Endeavour is designed to allow easy access from a remote location. Through the use of standard protocols and connections, the Gas Endeavour behaves like any other unit on an internal network, secured by a user definable password. All interactions with the software are conducted through a web browser using any computer. Thus, experiment monitoring can be carried out with any smartphone or tablet.

To extend the test capacity, multiple Gas Endeavour devices can also be easily connected via a local network device and operated from the same web browser.

Stable and reliable operation

Stable and reliable operation

The internal software of the Gas Endeavour runs on an embedded ARM CPU utilising the Linux operating system. This provides for an unmatched stability, data protection, and minimum downtime. Thus, users will never experience data loss under normal operating conditions, which is always a risk with PC based solutions.

Software updates issued by Bioprocess Control can be installed by the user in a controlled and easy manner.

A simple and intuitive software application

A simple and intuitive software application

The Gas Endeavour software application has been specifically designed to be applicable for a wide range of batch tests where gas volume or gas flow needs to be accurately and precisely measured. This software application, which is easy to understand and navigate, allows users to set up an experiment, monitor its progress, and download results with little effort. Moreover, all data is in a standard format that allows for easy analysis. The software application is simply a natural extension of the hardware platform that has been designed for carrying out various batch tests where gas flow, gas volume, and composition measurements are important.

Total control throughout an experiment

Total control throughout an experiment

The Control feature of the Gas Endeavour software application allows users to control the status of each batch test in real-time during an experiment. For the system with our multifunctional agitation system, users can control the interval, speed, rotation directions, and on/off time of the mixing of reactors, to ensure each reactor is operated under optimum mass transfer conditions. Users can also easily start, pause, and stop data acquisition of an ongoing experiment at any time by means of a simple to use control feature, which also indicates the status of each test line at all times.

Overall, this allows users to have optimal control of all test vessels and batch experiments at all times with the simple click of a virtual button from the software user interface.

See your experiment in real-time and anywhere

See your experiment in real-time and anywhere

The Graph feature of the Gas Endeavour software application and embedded web server allows users to see their experiment in real-time and from any location. Users can easily monitor the accumulated gas volume and flow rate of each reactor in real-time by selecting and viewing only the one they wish to see.

All values displayed are already adjusted for gas volumes normalised to 1 atmospheric pressure, 0 oC, and zero moisture content. Moreover, if a flush gas with a different gas composition from the produced gas is used to establish initial headspace gas conditions, the impact of the flush gas is also taken care of by the Gas Endeavour software application.
