It's been a delicate, nerve-racking dance for publishers to play the platform game, and it's even caused some rivalries to transform into alliances.When used in a smart way, pop-up forms can be a powerful tool for growing audiences, generating leads, and creating loyalty.To evaluate the expected multi-isotope ratio measurement capabilities of the system used, several isotope ratios spanning a wide range (Pb) were measured simultaneously, using a synthetic multi-element standard as sample.

Energy Dispersive X-ray Fluorescence (EDXRF) spectrometry is a versatile analytical technique that can satisfy both of these needs: it is non-destructive, requires very little sample preparation and can be configured to handle any sample size from a large surface to a few microns.

If you have a Mail Chimp account, you can easily set up a pop-up form on your Rebel Mouse site by following these simple steps: This is where you'll choose the format of your pop-up form, as well as when it should be displayed to people who visit your site.

You can also add and style field labels, call-to-action buttons, and custom messaging.

Most instruments scan across a range of mass numbers, measuring each isotope sequentially.

Because only one mass/ charge ratio is measured at a time, any fluctuations due to the sample introduction process, the plasma, or the detection system can introduce errors in the observed isotope ratios.
