Here's the fast, low-cost way to get an ultra-sensitive analysis for the ele ments present in a sample. It's Gulf General Atomic's ACTIVATION ANALY SIS SERVICE. Take a look. COST: A typical one-element, non-destructive analysis costs $20 per sample, in quantity. Some are as little as $6 per sample. METHOD: Samples are irradiated in one of Gulf General Atomic's TRIGA® reactors (reactor core shown above). The induced radioactivities are then identified and measured quantitatively, and the data are processed in GGA's computer center. SENSITIVITY: Limits of detection for over 70 elements range from 10/ig to 1 0 - 6 μg. Median sensitivity is approximately 10~ 3 μς (0.001 ppm in a one gram sample). PRECISION & ACCURACY: Typical accuracy in a routine analysis is ±2-4% of the value, with a precision in the range of ±1-3% of the value. SAMPLES: The technique is applicable to the analysis of virtually every con ceivable solid or liquid material, including ores, semiconductors, petroleum, water, polymers, solvents, biological tissues, and agricultural products. Most analyses can be performed without destroying the sample. CAPABILITIES: GGA's Activation Analysis Service is the largest, most com prehensive service of its type in the world. Analyses have been performed for over 600 organizations in the past eight years. Major facilities include three TRIGA reactors, several electron linear accelerators and neutron gen erators, and a UNIVAC 1108 computer. GET SPECIFIC DETAILS in terms of your analytical problem.
