mass spectrometry

Mass spectrometry is an analytical technique used to separate compounds based on differences in their molecular mass, as well as identify unknown compounds, quantify known compounds, and determine the structure and chemical properties of molecules. Common types of mass spectrometry (MS) include FAB (fast atom bombardment), ESI (electrospray ionization), MALDI (matrix assisted laser desorption), TOF (time of flight), FT (Fourier transform), and ICP (inductively coupled plasma). Mass spectrometry is also often combined with other analytical techniques, such as gas chromatography (GC) and liquid chromatography (LC).

Extension Activity with Isotopes Matter

// Sunday, October 9, 2016 • Michelle Okroy

After receiving positive feedback from Peter Mahaffy, the IUPAC project co-chair of Isotopes Matter, I decided to add an additional component to the original isotope assignment I posted.

Early Use of AP Insight with Honors Chemistry: Atomic Mass, Mass Spectrometry, and Dalton's Postulates

// Monday, September 12, 2016 • Allison Tarvin

College Board offers an excellent online resource for teachers and students. It's not free, but my school district pays the bill. AP Insight provides curriculum outlines, teaching ideas and resources, student handouts, and digitally-graded assessments.

Using IUPAC's Isotopes Matter as a Digital Learning Tool

// Monday, September 5, 2016 • Michelle Okroy

The first unit of chemistry, no matter your content sequence, is an opportunity to use formative assessments to identify student prior knowledge. In addition, this is also a time for your students to get an idea of your instructional approach and how they will be participating in class.
