The reason as to why M 1 V 1 = M 2 V 2 works when solving dilution problems is to be stated. Concept Introduction: The atomic mass of an element is defined as the sum of the number of protons and the number of neutrons. Molar mass of an element is determined from the atomic mass of an element. The moles of any element is calculated by the formula, Moles = Mass g Molar mass Molarity is used to find out the concentration of solution. The formula to calculate molarity is, Molarity = Number of moles of solute Liters of solution .

In an effort to reduce costs and increase the accessibility of instruments that utilize spectrophotometric detection, some researchers are beginning to experiment with 3D-printed parts. One example of this is the 3D-printed flow cell, shown at right. This device was made using polylactic acid and accommodates a LED at one end and a detector at the other. It can be used for standalone flow injection spectrophotometry or coupled to a chromatographic separation to be used as a detector. Explain why the sensitivity varies with the length of the flow cell, as shown in the data below. Could this setup be used for fluorescence analysis? Why or why not?

The dark lines in the solar spectrum were discovered by Wollaston and cataloged by Fraunhofer in the early days of the 19th century. Some years later, Kirchhoff explained the appearance of the dark lines: the sun was acting as a continuum light source and metals in the ground state in its atmosphere were absorbing characteristic narrow regions of the spectrum. This discovery eventually spawned atomic absorption spectrometry, which became a routine technique for chemical analysis in the mid-20th century. Laboratory-based atomic absorption spectrometers differ from the original observation of the Fraunhofer lines because they have always employed a separate light source and atomizer. This article describes a novel atomic absorption device that employs a single source, the tungsten coil, as both the generator of continuum radiation and the atomizer of the analytes. A 25-μL aliquot of sample is placed on the tungsten filament removed from a commercially available 150-W light bulb. The…
