A toxicologist testing shellfish for dioxin contamination and an art historian trying to authenticate a newly discovered Rembrandt might turn to mass spectrometry, a technique for determining the chemical makeup of samples. MassSpectator, a new Web calculator from the National Institute of Standards and Technology in Gaithersburg, Maryland, simplifies a key step in the analysis of mass spec results. Users enter output from a mass spec run, and the calculator specifies the location and size of the peaks—a step usually performed manually.∼wallace/MassSpectator_intro.html
