The purpose of this model is to provide an atomic absorption analyser having a low detection threshold, a wide dynamic spectrum and a simplified structure. To this end, the mercury atomic-absorption analyser of the present invention comprises a resonance radiation source located between the pole ...
1.Taking petroleum sodium sulfonate as sodium organometallic compound,the lower freezing point base oil as the prepared oil,the organo-sodium standard substance used for atomic spectrum was developed and calibrated with the one made by America CONSTANT Corporation.介绍原子光谱用有机钠标准物质的研制。
A. C. Menzies (see NATURE, Oct. 5, 1929), of the continuous background in the spectrum which overpowers all but the strongest Raman lines, is, however, serious, as it interferes with the general utility of the method. During the past two months I have been engaged in an attempt to ...
elemental composition of an analyte by its electromagnetic or mass spectrum. Several analytical techniques are available, and selecting the most appropriate one is the key to achieving accurate, reliable, real-world results. Proper selection requires a basic understanding of each technique ...
atomic spectrum - (physics) a spectrum of radiation caused by electron transitions within an atom; the series of spectrum lines is characteristic of the element natural philosophy, physics - the science of matter and energy and their interactions; "his favorite subject was physics" spectrum - an...

Be able to answer for a different reaction, number, set of conditions, etc. Questions Which form of electromagnetic radiation has the longest wavelengths? A line in the spectrum of atomic mercury has a wavelength of 254 nm. When mercury emits a photon of light at this wavelength, what is ...
(a) The atomic energy level spectrum and optical frequency spectrum of the modulated diode laser. The CPT resonance is excited when the frequency splitting, ν0 = nfm, between two components of the diode laser optical spectrum is equal to the atomic ground-state hyperfine splitting, νeg–-ν...
