What are applications of Oxygen-18 Gas (¹⁸O₂)?

Oxygen-18 Gas, a highly enriched stable isotope of oxygen, has several critical scientific and industrial uses. It is primarily used as a tracer in life sciences, a precursor for labeled compounds, and a reference standard in advanced research.

Medical & Biological Research (Tracers): It is used in metabolic studies and breath tests. For example, it can be used to synthesize ¹⁸O-labeled water (H₂¹⁸O) or other labeled biological molecules for Positron Emission Tomography (PET) and metabolic imaging.

Scientific Research (NMR & Spectroscopy): Used in advanced analytical chemistry, particularly as a source for ¹⁸O-enriched materials for Nuclear Magnetic Resonance (NMR) spectroscopy and Mass Spectrometry (MS) calibration.

Pharmaceutical & Chemistry: Used as a precursor for synthesizing ¹⁸O-labeled compounds to trace reaction mechanisms and study drug metabolism (pharmacokinetics).

Advanced Materials & Semiconductors: Utilized in the research and manufacturing of semiconductor materials and special optical materials, where precise oxygen isotope composition is required.

Packaging & Delivery Options

Frequently Asked Questions (FAQs)

Q1: Are you a manufacturer or a trading company?

A: We are a direct manufacturer with our own production facilities. This ensures the best quality control, stable isotopic enrichment, competitive pricing, and a reliable supply chain directly to you without middleman markups.

Q2: Is Oxygen-18 Gas hazardous?

A: Yes, as a compressed gas, it is classified as a dangerous good for transport (Class 2.2 Non-flammable, oxidizing gas). While the isotope itself is stable and non-radioactive, high-pressure cylinders must be handled with care. Oxygen is an oxidizer and supports combustion, so it must be kept away from oils, grease, and open flames. Proper ventilation and use of standard gas regulators are required.

Q3: Do you offer international shipping?

A: Yes. We ship globally with a reliable logistics network. We handle all necessary documentation, including Dangerous Goods (DG) declarations and customs clearance, to ensure smooth delivery. The product is packaged in specialized high-pressure cylinders to guarantee safe and secure transport to your destination.

Q4: What industries do you supply Oxygen-18 Gas to?

A: We supply high-enrichment Oxygen-18 Gas primarily to the Life Science Research Industry, Pharmaceutical & Biotech Companies (for labeled compound synthesis), Analytical Testing Laboratories, and Advanced Material / Semiconductor Research.

Q5: What is your Minimum Order Quantity (MOQ) and do you provide samples?

A: Our MOQ is flexible. We can accommodate small quantities for R&D purposes ( 0.2L or 0.5L) as well as bulk orders. We can also provide samples or small volume testing for your strict quality and enrichment verification upon request.

Q6: What packaging options do you offer?

A: We supply Oxygen-18 Gas in high-pressure aluminum or stainless steel cylinders in various sizes (0.2L, 0.5L, 1L, 2L, etc.) to suit small R&D needs and larger commercial production volumes. All cylinders are equipped with standard CGA or DIN valves.

Q7: How fast can you deliver?

A: Lead time depends on quantity and destination. We maintain strategic stock of standard specifications and have global logistics experience serving multinational customers worldwide.
