Zero Air Gas systems for Gas Chromatography employe a four step process including filtration, hydrocarbon removal, cooling and final filtration to produce the required level of purity. Two stages of high efficiency coalescing pre-filtration are employed to remove oil and particulate contamination. The air is then passed through a heated catalysis module to oxidize hydrocarbons into carbon dioxide and water. The air is then cooled and passed through a final membrane filter to remove all particles >0.01 micron.

In line with steady increase of CO2 laser usage in welding-cutting technology as well as excimer Laser application in semiconductor and medical field in the country, We pays due attention in this specific field of Specialty gas sector.

Specialty gases needs dedicated gas handling equipment and proper gas distribution system to ensure gas quality remain in equilibrium between the source and the point of use. We has on offer a wide array of equipments including Pressure Regulators, Gauges, Valves and Gas Manifold systems among many others in different specification.

It is important to use right Gas Pressure regulator in high pressure gas cylinders as a wrong choice may result in impurity or malfunctioning. Improper pressure regulation can cause fluctuation of flow which may further cause undesirable result. BOL has variety of pressure regulators which can be specifically used for different types of specialty gases. Send your enquiry mentioning service, working pressure and flow.

Apart from our products, We also offer consultancy services for gas handling, gas distribution and training. We have on panel specialists who have a range of multi functional skill sets for developing solutions for different types of gas related projects. You can rely on we to find the most suitable solution for your specific requirements for gas distribution and safety training while handling equipment.

Cylinders filled with Industrial and Medical Gas have to be hydrostatic pressure tested every five years. The cylinders have to be tested for strength and leaks. The hydrostatic pressure test involves filling the cylinders with water and pressurization of the cylinders in order to test the pressure. The pressure tightness can be tested by shutting off the supply valve and observing whether there is a pressure loss. We can hydrostatic pressure test various types and sizes of cylinders at our testing station. We are the few who are certified and have the facility to test HYDROGEN and other Gas Cylinders.

Oxygen can support life in hospitals. It is noncombustible and is also used in industry which will actively support the burning of combustible materials. Some materials that will not burn in air will burn in oxygen. Materials that burn in air will burn more vigorously in oxygen. As a non-liquid gas it is shipped at pressures of 2000 psi or above. Pure oxygen is nonflammable. Under prolonged exposure to fire or intense heat the containers may rupture violently. Oxygen is used in the production of synthesis gas from coal, for resuscitation and as an inhalant.

Argon has many different applications in many industries. The most common one is as a shielding gas for arc welding – either in pure form or as part of various mixtures. It is one of the main gases used in filling mixtures for incandescent (filament) lamps, phosphorescent tubes and thyratron radio tubes. It is also used as a carrier gas in chromatography, sputtering, plasma etching and ion implantations. It provides a blanket atmosphere in crystal growth, viniculture and pharmaceutical packaging. For excimer lasers, argon is blended with fluorine and helium. As an insulation gas, argon is a popular way of improving thermal insulation in multi-pane windows.

It is the only fuel gas that does not contain any carbon atoms. H2 has the highest thermal conductivity of all gases. Combined with oxygen, the hydrogen flame reaches a temperature of 2834°C. It is often mixed with argon to create a range of argon/hydrogen shielding gases for TIG and plasma welding. These shielding gas mixtures are primarily used for welding austenitic stainless steels and some nickel alloys. Hydrogen can also be used with argon in a range of gas mixtures for plasma-cutting (stainless steel and aluminum mainly). In addition, it can be combined with oxygen for underwater flame-cutting. Deeper cutting applications require higher fuel and oxygen pressures.

One of the main applications of nitrogen is blanketing, purging and sparging in the food and chemical industries. It can also be found in modified atmosphere packages (MAP) for foodstuffs. In liquid form, it is an agent to shock-freeze food, store biological material, perform cryosurgery and cryogenically grind plastics and rubbers, for instance. In the semiconductor industry, N2 is used in large quantities as a purge and carrier gas. In electronics, it acts as an inerting agent for epitaxial reactors. It is also useful as a carrier, zero and balancing gas in laboratory analysis. Other common applications include heat treatment, the production of ammonia, fire extinguishing in mines, tyre filling, shrink-fitting and cold traps, where nitrogen can help to increase vacuum efficiency.

Carbon dioxide has many well-known applications in the food and beverages industry – from carbonating drinks and conserving wine to modifying atmospheres for packaged foods. Dry ice – or solid CO2 – is commonly used for storage and transportation of temperature sensitive products such as frozen/chilled foods or medical/ pharmaceutical materials. Dry ice is used as a process coolant in food, chemicals, research and pharmaceutical industries and is also an extremely effective and environmentally sound cleaning agent. In agriculture, CO2 can be used to enhance growth in greenhouses and as a feedstock for algae that produce bio-oil (green crude). The non-flammable properties of CO2 make it a popular pressurizing gas for everything from aerosols through fumigants to air guns.

We do have the perfect solution for ultra high pure gas requirement particularly as Carrier Gas or Zero Gas in varied applications of GC and other measuring instruments related to their fields.
