What is Methane-¹³C (¹³CH₄)?

Methane-¹³C (¹³CH₄) is a molecule of methane in which the carbon atom is the carbon-13 isotope (¹³C) rather than the more common carbon-12 (¹²C). It is a colorless, odorless, and highly flammable gas, lighter than air, with a molecular weight of approximately 17.03 g/mol (ordinary ¹²CH₄: ~16.04 g/mol). This small mass difference makes ¹³CH₄ an exceptionally powerful non-radioactive stable isotope tracer for tracking carbon atoms through complex environmental, chemical, and biological systems.

What are applications of Methane-¹³C (¹³CH₄)?

Methane-¹³C (¹³CH₄) serves as an exceptional, non-radioactive stable isotope tracer. Because the ¹³C isotope has a natural abundance of only ~1.1%, it provides a highly distinguishable signal, making it an ideal tool for tracing carbon pathways in complex biological, industrial, and environmental systems.

1. Medical Diagnostics

Methane Breath Tests: ¹³CH₄ is used in advanced breath testing to evaluate gastrointestinal health. By tracing the metabolic activity of methanogenic bacteria in the gut, clinicians can non-invasively assess conditions such as Small Intestinal Bacterial Overgrowth (SIBO), irritable bowel syndrome (IBS), and overall microbiome balance.
Precision Tracing: The stable isotope allows for high-precision monitoring of methane production and absorption dynamics within the human digestive system without any radioactive risk to the patient.

2. Semiconductor Manufacturing

Thin-Film Deposition and Doping: ¹³CH₄ is utilized in the fabrication of advanced semiconductor devices at the 14nm technology node and below. It acts as a highly pure carbon source for thin-film deposition (such as in SiC or carbon-based hard masks) and precise carbon doping processes.
Process Control & Failure Analysis: The stable isotope can act as an internal marker to trace carbon incorporation, helping engineers optimize deposition parameters, reduce defects, and analyze material structures at the atomic level in cutting-edge microchips.

3. Scientific Research

Biomarker Research: In biological studies, ¹³CH₄ is an ideal material for tracking specific metabolic pathways of methanogens and studying microbial interactions in complex ecosystems (like the rumen or soil).
Environmental Tracing & Carbon Cycle: As a potent greenhouse gas, tracing the origin and fate of methane is critical. ¹³CH₄ is used to distinguish between anthropogenic and natural emission sources, study atmospheric degradation, and trace carbon migration in wetlands, agricultural sites, and marine environments.
Analytical Calibration: Used as a standard reference material in advanced mass spectrometry to calibrate instruments for precise isotopic ratio measurements.

Packaging & Delivery Options

Standard Package: 0.25 L, 1 L, 2 L, 5 L, 10 L high-pressure cylinders.

Frequently Asked Questions (FAQs)

Q1. What is Methane-¹³C (¹³CH₄)?
A: It is a special type of methane gas. The carbon inside it is a natural, slightly different kind of carbon (Carbon-13) that can be easily detected by special machines. This makes it very useful for tracking where the gas goes.

Q2. What is it mainly used for?
A: It is used in Medical Diagnostics, Semiconductor Manufacturing , and Scientific Research . Researchers use it to track how carbon moves and changes in different processes.

Q3. Is it natural or radioactive?
A: It is completely natural and not radioactive at all. Carbon-13 is naturally found in all living things and everyday materials. We simply concentrate it to make this product.

Q4. How should it be stored?
A: It must be kept in a securely sealed high-pressure gas cylinder. You should store it in a cool, dry, and safe place, away from fire, heat, and sunlight.

Q5. Is it safe to handle?
A: It is highly flammable and can be dangerous if it leaks in a closed room (it can replace the oxygen in the air). It must only be used by trained professionals in well-ventilated areas, away from sparks or open flames.

Q6. Is it bad for the environment?
A: Yes, methane itself is a greenhouse gas. While our product is used for research to help the environment, it should be handled carefully to avoid unnecessary leaks into the atmosphere.

Q7. Are there special rules for shipping it?
A: Yes. Because it is a highly flammable gas, it is classified as a hazardous material. It must be transported safely in approved containers by trained professionals.

Q8. Why is it useful for research?
A: It acts like a tiny “tracking tag.” Because special instruments can easily see it, scientists can follow exactly where the carbon goes during tests without disturbing the process.

Q9. Why choose this instead of regular methane?
A: You only choose this if you need to track the gas. It is not safer than regular methane—it is just easier for machines to detect. If you don’t need to track it, regular gas is enough.
