The periodic "law" of chemistry recognises that many properties of the chemical elements are periodic functions of their atomic number (the number of protons within the element's atomic nucleus). The periodic table is an arrangement of the chemical elements ordered by atomic number in columns (groups) and rows (periods) presented so as to emphasize their periodic properties. The element polonium is very much in the news at present, perhaps for the first time ever, and for the wrong reasons. This site does contain further information about polonium. Products & Services
Autosamplers are automated sample loaders, usually robotic, used with chromatography and other analytical technologies.
Nonferrous metals and alloys are not based on iron and include alloys of aluminum, copper, titanium, zinc, nickel, cobalt, tungsten, precious metals, refractory metals.
Specialty nonferrous metals and alloys include metals such as hafnium, zirconium, beryllium, tantalum or osmium with unique properties for specific applications.
Antennas are structures or devices used to collect or radiate electromagnetic waves.
Gas chromatography detectors (GC detectors) identify solutes as they exit the chromatographic column. A chromatogram is generated plotting the signal versus time.
