What are some considerations and strategies when working with fluorescing samples?

Fluorescent macromolecules pose an interesting challenge for analytical methods based on light scattering as the light emitted by the samples themselves can be detected as if it were scattered light. Learn what you may need to consider before working with fluorescing samples.

How can I tell if I have fluorescing or absorbing samples?

To accurately calculate the molar mass of a sample, we need to account for any excess light (fluorescence) or a decrease in the intensity of the laser source (absorbance) so these changes aren’t incorrectly attributed to the sample being analyzed. Learn more here.

How can I assess the quality of my chromatography in ASTRA?

Did you know that ASTRA® can be used to assess the quality of chromatography with statistics such as peak height, column plate count, peak width, asymmetry, and resolution? In fact, this analysis is built into every online method in the software so there’s no need to use your chromatography software to perform these calculations. This is particularly advantageous when using Wyatt’s HPLC Service to control your HPLC hardware or performing FFF-MALS experiments using VISION.

I plan to run my samples over the weekend. How can I have the instruments shutdown after the run completes if I’m not there?

Running samples overnight or during the weekend can help to improve the throughput of your experiments, but there are some considerations to make when leaving a system unattended. Learn how to make sure your instruments shut down properly here.
