- General: The elemental analyzer is available to all members of the Stanford community. This is a user run instrument. Before signing up, users must complete a training session on the instrument and be certified by a facility technician. Once certified, users planning to run samples must sign up on the EA Scheduler.
- Operation: The elemental analyzer is available for use by certified users Monday through Friday, 8am to 5pm.
- Cost: $4/sample
- Samples: Soils and plant material (or other compounds) should be ground to a powder for best results. Samples are then weighed into a tin capsule and carefully folded into a tight ball; commonly referred to as foil balls. The most common sized tin purchased for this instrument is a 5 x 9 mm tin which is item #041077 available from CostechAnalyticalTechnologies,Inc., or NC9155294/NC9437183 on SmartMart. We have tins available in EMF that can be used for small to moderate sized sample sets. Sample size varies with plants generally between 2 and 10 mg, and soils between 10 and 50 mg. Because of the small mass involved, duplicates are often run, especially with less homogeneous samples. Please note that at this time the instrument is configured to run N and C only.
- Standards: Results are based on the detection response of a chemical standard with know nitrogen and carbon content (provided by EMF).
- Detection Limits: ~0.1%
