Gas Purchase Policy at the ALS

Berkeley Lab instituted a new policy effective June 1, 1997, for the purchase of gases. This policy covers the purchase and delivery of standard industrial gases, specialty gases, and toxic and corrosive gases. ALS users should follow the guidelines below when buying gases for experimental use.

Standard Industrial Gases

A supply of the most commonly used gases at the ALS--He, Ar, N₂, and CO₂ (large cylinders, standard purity)--is available for users in the gas storage racks by Building 6. Users may remove a bottle for use once they have signed for it in the Gas Log Book at the User Services Area in Building 6, and have placed the copper ring from the bottle on the hook beside the log book. When filling out the Gas Log, users must provide the following information: the date; their name and their account number; the beamline or lab where the gas is to be used; and the type of gas and the quantity (number of bottles) taken. ALS staff will reorder additional cylinders based on this information in order to maintain a readily available supply of common gases for all users.

All other standard industrial gas purchases can be ordered by contacting a Beamline Coordinator (ext 7464) or an ALS Receiving staff member (ext. 4494). Gas cylinders will be delivered to the gas storage racks at the ALS (or the building specified by the purchaser). All gas cylinders delivered to the ALS will be labeled with the name of the user or group who ordered them. Users ordering large cylinders should record their purchases in the Gas Log Book in the Building 6 User Services Area.

Below are some examples of available gases and their prices; a complete list of gases for purchase can be found in the User Services Area in Building 6.

Specialty Gases

Berkeley Lab Chemical Inventory

All gas bottles and cylinders at the ALS must be identified with bar code and logged into the Berkeley Lab Chemical Inventory by ALS staff. The inventory will be updated periodically; for more information contact Beamline Coordination Section Leader (ext. 5527).
