3 Step Purity Protection

  • 1 Specialty packagingThe only DOT approved LP 239 SS Cylinder available on the market today. Eliminates rust / particulate present in carbon steel cylinders. Compliant with California Code of Regulations, Title 17 Division 1 Chapter 13 §40242 (b).
  • 2 Process controls – Specialized process to maintain purity from start to finish. Each cylinder is subjected to a proprietary cleaning process prior to filling, which eliminates residual oils, particulates, metal shavings, weld slag and mill scale present from the cylinder manufacturing process. * In a cleanliness test conducted by a third party, the stainless steel cylinder had significantly less residual oil and particulates than a standard carbon steel cylinder.
  • 3 Analysis / Traceability – Analysis after each step to ensure purity and maintain quality. Cylinder serial # listed on certification (COA).

1. Specialty Packaging – Stainless Steel Cylinders

Gas Innovations Specialty Gas Cylinders:
  • Compliant with California Code of Regulations, Title 17 Division 1 Chapter 13 §40242 (b).
  • Corrosion resistant. Free of metal particulate “black flakes”.
  • Undergo strict process controls to ensure quality.
  • Virtually no residual oil / contaminants.

Carbon Steel Industrial Gas Cylinders:
  • Internal cylinder wash.
  • Specialty valving procedures.

* Carbon steel cylinders can break down over time introducing non-volatile residue (rust) and other contaminants.

Top Filling – Filling gas product on top of residual gas & unknown contaminants.

 Gas Innovations Refill Procedures:

Evacuation - Residual product removed
Inspection - Internal wash if necessary
Vacuum - Remove air / moisture.
Fill - Max allowed by DOT.
Analysis - Certified product (COC).

Examples of residual oils / unknown contaminants. * Note a passive distillation may remove some solids but will not remove contaminants with similar chemical composition (ex. Benzene, Hexane).

Specialty Valving Procedures

Gas Innovations also implements specialty valving procedures to minimize contamination. Valving is an abrasive process, and multiple de vales and re valves should be avoided. Each time a cylinder is de valved / re valved it can jeopardizes the integrity of the valve threads and introduces metal / debris into the cylinder.

3. Analysis / Traceability

Filled tank

Guaranteed Quality / Traceability. Gas innovations onsite laboratory uses FID (Flame ionization detector) to certify product at parts per million (PPM). Cylinders are tested after fill to ensure quality. Certificate of conformance (COC) list your cylinders serial #’s ensuring products meets purity standards. Competitive products only reference source material, not what's in your cylinder. No analysis, no traceability.

*GI utilizes a dedicated cylinder fleet for high purity solvents. This eliminates cross contamination and unknown impurities that can be introduced from different industrial applications.

Certifications and Analysis

  • We provide comprehensive analytics quality control.

  • Each order is accompanied by a certificate of conformance at no additional charge.

Frequently Asked Questions:

Q: Is there such thing as Food Grade / Medical Grade butane?

A: There is no food grade or medical grade butane (Just deceptive marketing). The industry standard for extraction solvents is 99.5%+ non odorized products. It important to have a complete analysis (COA) at PPM certifying the products purity and listing any impurities. *Be on the look out for benzene and hexane as they are toxic for consumption.

Q: What is top filling a cylinder?

A: Top filling is refilling a cylinder that has not been evacuated, and put under vacuum.  Instead gas product is filled right on top of residual product and unknown contaminants. This is common among industrial gas filling operations. See Gas Innovations Refill Procedures above for more information. Top filling into cylinders leads to inconsistent purities, uneven mix ratios and unknown contaminants.

Q: What is causes black flakes / particulate in my cylinder?

A: This particulate is left over from the cylinders manufacturing process. All carbon steel cylinders rust over time and is accelerated in the presents of moisture. These solvents do their job and will dissolve any non-volatile residue (rust) from the cylinder wall. An internal wash can minimize this, along with an in line micron filter. To eliminate particulate and residual oils we would recommend a stainless-steel cylinder as is used in most critical applications.

Q: Why is purity important?

A: Higher purity the product, is more consistent product. Meeting higher purities like 99.5%+ requires the removal of impurities and contaminants. Lower purity products vary in purity and can have higher amounts of harmful contaminants ( ex. BTEX, C6+, Hexane, Alcohols & Acetone).

Q: Do I need to distill my products?

A: Gas Innovations products are pre distilled and ready for use. The term “distillation” in the extraction community is more of a “passive distillation” which is filtration. This may remove some solids/ particulate but will not eliminate contaminants with a similar chemical composition (ex. Benzene). Save downtime with GI’s guaranteed pure products.
