The Haber-Bosch process for reducing N2 gas to ammonia (first developed for producing munitions) requires a temperature of 500C, a pressure of up 300 atmospheres and a catalyst to break that pesky triple bond. Rhizobia do the trick under ambient conditions and for benign purposes. We can learn a lot from microbes.

The traditional acetylene reduction assay — for decades the standard method for measuring nitrogenous activity — has well-documented limitations. Acetylene inhibits the key enzyme involved in N2-fixation by reducing the permeability of a barrier to O2 diffusion in the legume nodule, thus limiting the ATP production required for the energy-expensive reaction.

Direct measurement of H2 evolution, the natural by-product of nitrogenase activity, provides a more reliable method. Our Q-Box NF1LP Nitrogen Fixation Package measures H2 gas evolved by nodulated legume roots directly. The method used by Qubit scientists has shown that published rates of in vivo nitrogenous activity can be underestimated by more than 80%—something of a large error.

Visit us at the North American Symbiotic Nitrogen Fixation Conference at Queen’s University, Kingston, On June 1st to 4th.

That's a wrap on ACSM 2026! 👏

Thank you to everyone who stopped by the Qubit booth this week. It’s always a pleasure to talk metabolic measurement with people who care about data accuracy as much as we do.

If you didn't get a chance to see VOCO in person, or you want to dig deeper into what it can do for your research or training programs, we're happy to walk you through it. Contact us via the link here: https://www.voco-cpx.com/contact

Until next year.

Soil is not a passive substrate. It is one of the most metabolically active environments on the planet, hosting microbial communities whose collective respiration releases CO2 at rates that meaningfully influence global carbon budgets.

This is vitally important, particularly at a time when carbon accounting has become politically contested. Rough estimates are not sufficient. The numbers need to be accurate and defensible.

Qubit's soil respiration system allows researchers to measure CO2 flux in situ, with sensor stability and precision that field conditions demand. Sensors for CH4, N2O, H2 and NH3 can be added, and all gases monitored simultaneously on the same data acquisition platform.

Soil is critical for survival. Let’s get to understand it better.

We had another fantastic day in Salt Lake City, exhibiting at ACSM 2026. The conversations have been insightful, as always.

There's a lot of interest in what "accurate metabolic data" actually means in the field, on a treadmill, or on the track. That’s why we designed VOCO as a cost-effective, wearable CPX device that can be trusted to provide accurate data anywhere..

Still one more day left.

Visit us at Booth #105 to see VOCO in action.

We landed in Salt Lake City last night, and have had a great first day of exhibiting at ACSM 2026!

This year's theme is physical activity, exercise, and technology, which puts metabolic measurement squarely in the conversation. How do you know a wearable CPX device iis actually measuring what it claims to measure? Validation matters. Calibration matters.

VOCO has been validated against a gold-standard metabolic calibrator and has an autocalibration routine that keeps your data accurate during use. If you're at the show this week and want to talk methodology, find us at Booth #105.

We are exhibiting at the American College of Sports Medicine Annual Meeting in Salt Lake City this week, May 26-29.

We will have VOCO on display, our wearable breath-by-breath CPX system for VO2 and VCO2 measurements in lab and field conditions. Validated. Lightweight. Priced for the world outside hospital procurement budgets.

If you are attending, stop by the Qubit booth. We are scientists who build instruments, and we find that the best conversations start with a researcher who has a scientific problem we haven't come across before.

We'll do our best to help. Or at minimum, we’ll enjoy sharing an interesting discussion with our bright and enthusiastic clients.

Consumer wearables estimate VO2 max using heart rate models built on population averages. Which is to say, they tell you approximately what someone vaguely like you might be capable of, under assumptions that may or may not apply to you personally.

Direct measurement of gas exchange during exercise tells a different story: your actual aerobic capacity, your respiratory exchange ratio, your ventilatory thresholds, your real caloric burn rate. Numbers that belong to you specifically, derived from what your body is actually doing rather than what a model predicts.

VOCO measures all of this. Wearable. Field-ready. Validated against medical-grade metabolic carts. Affordable enough that the price is not the reason to say no.

If you are serious about understanding human performance, the data should be serious too.

We are one week out from ACSM 2026 in Salt Lake City, where Qubit Systems will be showcasing our VOCO device (among other products for human metabolic studies).

If metabolic measurement is part of your work, VOCO is worth a look at our booth.

Here's where VOCO stands out:
• Validated against a gold-standard metabolic calibrator
• Wearable and field-deployable
• Measures VO2, VCO2, RER, and calorific burn rate during rest and exercise
• Android app, desktop app and comprehensive 9-panel Wasserman plots.
• Accurate for research. Practical for everything.

We're not reinventing the wheel, we're just making it portable.

Find us at booth #105 to see the data for yourself.

One of the most satisfying aspects of developing Qubit technology to monitor metabolic and physiological processes is meeting the challenges that scientists put before us:

“We need to monitor seal respirometry in the Arctic…” No problem!

“Can you measure CO2, O2, CH4 and H2 exchange in an elephant?” Yes!

“From the mouth and the trunk separately?” Sure!

“Can you design a system for measuring photosynthesis and respiration of coral underwater on the reef?” Easy!

“…while monitoring chlorophyll fluorescence?” Obviously!

“...and calcification and decalcification?” Thought you’d never ask!

“I want to measure emissions of CO2, CH4, N2O, and H2 from soils in the field.” The field or anywhere else - up to you!

“My data must be publishable in high-impact journals.” Then you’ve come to the right place!

If you have an experimental challenge, let us know!

VO2 measurement in field settings has a few persistent problems that don't get talked about enough.

👉 Metabolic carts work well for standard tests under controlled conditions, but can’t be used for CPET during sports activities.
👉 Some wearable alternatives trade accuracy for convenience. Sometimes a lot of accuracy.
👉 The data you get is only as useful as the system's validation. Devices must validated against a recognised gold standard, not just compared to each other.

VOCO was built specifically to address all three issues. It's a wearable metabolic analyser validated against a gold-standard metabolic calibrator and medical-grade metabolic carts. It provides equivalent or better accuracy than systems that cost significantly more.

If you're attending ACSM in Salt Lake City this month, come see it in action on Booth #105.
