Protocol for analysis of stable isotope on Kiel 253
Introduction
The following protocol describes the analysis of carbonate samples for δ13C and δ18O at a Kiel IV carbonate device.
Safety info
Wear cryo-gloves, long sleeve shirts, protection glasses and closed shoes when handling with liquid nitrogen in open dewars. Liquid nitrogen is an extremely cold material. The vapor of liquid nitrogen can rapidly freeze skin tissue and eye fluid, resulting in cold burns, frostbite, and permanent eye damage even by brief exposure.In the event of spillage of liquid nitrogen on a person
If exposed to liquid or cold gas, restore tissue to normal body temperature, 37°C, followed by protection of the injured tissue from further damage and infection. Remove or loosen clothing that may constrict blood circulation to the frozen area. Rapid warming of the affected part is best achieved by using water at 42°C. Water should under no circumstances be over 44°C, nor should the frozen part be rubbed either before or after rewarming. If in doubt contact Legevakt (phone 116 117 or 113 for emergencies).
If someone get liquid nitrogen it in the eyes, call 113, wash the eyes with appropriate equipment immediately.
Sample identification
A sample list should first be made: total amount of samples, Sample ID (from user), type of material, Lab ID (project no) ect. The analyses project must be registered in the project database http://delta.geo.uib.no:8085
