This chapter discusses the relative atomic masses, molecular masses, and the mole concept. The relative atomic mass of an element is defined as the weight in grams of the number of atoms of the element contained in 12.00 g of carbon-12. To calculate the relative atomic mass of chlorine, th...
The quantitative analysis of halogenated dibenzo-dioxins and -furans in biological (and environmental) matrices is a good example of the combination of high resolution GC (HRGC) and MS (HRMS) technologies using the isotopes of chlorine and carbon to facilitate identification and quantification. Prior...

The spectra produced from introduction of the analytes in a liquid matrix, with and without chlorine present, contain a number of ions that arise through secondary processes including breakdown and adduct formation. Sample introduction into an APCI source in air, via a heated-plate inlet with a ...
Results and Discussion CID-MS/MS Analysis of Piperazimycins A and B The strong antibiotic and cytotoxic activity of the crude extract was in part due to staurosporine [16]. Two further highly cytotoxic antibiotics were identified as chlorine- containing peptides by their formulas C31H47N8O10Cl...
Potassium and chlorine bond to form potassium chloride. Potassium ions have a +1 charge and chloride ions have a -1 charge. They stick together in a 1:1 ratio giving us the formula KCl.Answer and Explanation: Become a member and unlock all Study Answers Start today. Try it now Create ...
Deprotonated and chlorine adducts ([M − H]−, [M + Cl]−) are considered for negative polarity mode, while protonated, sodium and potassium adducts ([M + H]+, [M + Na]+, [M + K]+) are considered for positive polarity mode. Given a database mass M∈...
