An ECD has a limited [clarification needed] dynamic range and finds its greatest application in analysis of halogenated compounds. [9] The detection limit for electron capture detectors is 5 femtograms per second (fg/s) and the detector commonly exhibits a 10,000-fold linear range.
The T-meter had a system of thermistor probes, each of which plugged into the base of the unit and able to accurately measure a variety of temperature ranges. [8] The T-meter found widespread acceptance in scientific laboratories and industrial plants. [6] In 1976, ECD earned over US$200,000 in sales and had a backlog of orders worth $1,500,000 ...
The chosen content of zinc depends on the required productivity and part configuration. High zinc improves the bath's efficiency (plating speed), while lower levels improve the bath's ability to throw into low current densities. Typically, the Zn metal level varies between 20 and 50 g/L (2.7-6.7 oz/gal). The pH varies between 4.8 and 5.8 units.
[8] ECD produces significantly different types of fragment ions (although primarily c- and z-type, b-ions have been identified in ECD [9]) than other MS/MS fragmentation methods such as electron-detachment dissociation (EDD) (primarily a and x types), [10] [11] [12] collision-induced dissociation (CID) (primarily b [13] and y type) and infrared ...
Anchor channels, invented by Anders Jordahl in 1913, are steel channels cast flush in reinforced concrete elements to allow the installation of channel bolts for the fastening of components. Anchor channels consist of steel C-shaped channels and anchors (mostly headed studs ) which are connected to the channel by welding or riveting/forging.
These plaques can flake off, leading to visible impurities in water and a slight metallic taste. The life expectancy of galvanized piping is about 40–50 years, [12] but it may vary on how well the pipes were built and installed. Pipe longevity also depends on the thickness of zinc in the original galvanizing, which ranges on a scale from G01 ...
Galvanized fumes are released when the galvanized metal reaches a certain temperature. This temperature varies by the galvanization process used. In long-term, continuous exposure, the recommended maximum temperature for hot-dip galvanized steel is 200 °C (392 °F), according to the American Galvanizers Association.
Galvanized mild steel cable ladder with corrosion around stainless steel bolts All metals can be classified into a galvanic series representing the electrical potential they develop in a given electrolyte against a standard reference electrode.
