Determination of trace metals in fresh water mussels by atomic absorption spectrometry with direct solid sample injection

Comparison between neutron activation analysis and graphite furnace atomic absorption spectrometry for trace aluminum determination in biological materials

“…There has been increasing evidence in recent years indicating that aluminum is involved in human metabolism and disease (1, 2). Currently in the literature there are several reported techniques involving destructive neutron activation analysis (3-6) and atomic absorption involving both direct injection of sample or preinjection wet chemistry (7)(8)(9)(10) for the determination of aluminum in biological matrices. However, because of aluminum's ubiquity both in the environment and in reagents as well as its intractable chemical nature, there exists discrepancies among various reported values employing different techniques.…”

The Effects of Sulglycotide on the Adhesion and the Inflammation of Helicobacter Pylori

“…Gastric mucin is an essential component in the mucosal barriers against a variety of insults. The mucosal defense system protects from mucosal injuries to maintain elasticity and permselectivity of the mucus gel and interferes with H. pylori colonization [22,23]. The maintenance of the mucous layer's mucosal defense system and mucinous contents are affected by diverse gastroprotective agents including sulglycotide [24].…”

Background reduction during direct atomization of solid biological samples in atomic absorption spectrometry

“…With unashed samples, only 0.1 to 0.3 mg can be analyzed (2). A charring cycle at 773 K diminishes background and allows several milligrams to be run, but 50% suppression of lead signals is common (1, 3) while over 1000% enhancement of zinc has been observed (3) when using direct aqueous standardization. Standard additions are often used (4).…”
