About

NMR Solvent Peaks

This utility helps organic chemists quickly identify potential impurities by searching a database of NMR data. Users can input solvent, peak multiplicity, and location to find candidate impurities. It supports both proton and carbon data searches.

Highlights
  • Search for impurities by mode, solvent, multiplicity, and ppm
  • View alphabetical list of all impurities
  • Adjust user interface handedness
  • Select color themes
  • Supports proton and carbon NMR data

NMR Solvent Peaks is a conveniently-searchable version of the ungainly table of NMR data most organic chemists keep a copy of nearby. Instead of searching through the table for a peak near your unidentified peak, just enter your solvent and the peak's multiplicity and location and you'll have a short list of candidate impurities. NMR Solvent Peaks has support for searching both proton and carbon data, and references the widely-distributed 2010 Organometallics paper by Gregory Fulmer and coworkers and the 2016 OPRD paper by Gregory Whiteker and coworkers. Feature Highlights: - search for impurities based upon mode (proton/carbon), deuterated solvent, multiplicity, and ppm - select "show all" for ppm to see an alphabetical list of all impurities in the app's database - pick a color theme and adjust the user interface handedness

Augmented reality for a greatly improved daily routine in lab life! In our capacity as experts for purification, we aim to offer maximum working comfort as well as highest efficiency in your laboratory, that is why the goal of these app is to support you and to save you time day by day. Therefore our App allows for: -Automatic detection of your compounds and calculation of your Rf and ΔCV (=ΔK) values -Direct (and secured) information transfer to puriFlash® purification system and more precisely to our AI ”Genius” included in our software, which suggests the best method for a successful purification -Data archiving, if desired. The app can be used extremely intuitively and user-friendly. It is divided in 3 main categories : - Flash & Go: « New TLC » 1. Take a picture of your plate or download it via your library: The compounds are automatically detected. 2. Select the compounds of interest with just one click: The application calculates your Rf and ΔCV (=ΔK) values and indicates whether your Rf values are within a comfortable range for purification. From the smallest ΔCV obtained on your TLC plate, the application gives you the level of difficulty of the separation. 3. Enter the solvents, their proportions and your comments into the appropriate fields. 4. Send the TLC Information to an email address of your choice or directly to your puriFlash® system. - « MY TLC » for the retention of data. All information of your previous TLC plates are archived in a single location. In case you would like to reuse the parameters of the plate for a new separation, simply send them to any puriFlash® system with a single click. - « SETTINGS » to personalize your experience. Connect your smartphone with your puriFlash® via bluetooth or Wifi. Configurate your application according to your preferences. Quickly and directly access our internet sites. Notes: “TLC to Flash & Prep Chromatography” is a free application. Our wish was to enable everybody to use it freely. You can even use it if you do not possess a puriFlash® purification system. Nevertheless, your experience as an user may be reduced since our systems are equipped with a unique technology that allows for data exchange only within these systems. Therefore you cannot equally benefit from the “Genius” proposals with regard to the best methods for your purification. However, it is never too late to opt for excellence and discover our puriFlash® purification systems.
