Orders are accepted at any time.  Given the limited quantity of gas available, purchasers are restricted to one purchase every three years. The HCG Gas Reference Materials are distributed in 50 mL stainless steel vessels equipped with one (1) standard ¼” NPT fitting and pressurized to approximately 50-75 psi.  The HCG Gas Reference Materials are only sold as a set of three.

Individuals requesting to place an order for the HCG Gas Reference Materials will receive an order form to be completed in full and returned to Mirian Cuara. A user agreement form will then be sent to the purchaser for signature and must be returned to Ms. Cuara. Purchases by other agencies of the U.S. Government must be identified prior to completing the order form, as separate procedures apply.

Shipping

The USGS will arrange and cover the cost of shipping for orders within the US and Canada. Shipping to locations outside of the US and Canada are the responsibility of the purchaser. For international shipments, the purchaser is responsible for making all of the shipping arrangements and covering all of the expenses associated with international sample shipping.
