Eigenschaften
Automated NMR instrument calibration
AutoCalibrate monitors several key parameters, making sure users are always generating great data. These parameters ensure that users get the best signal-to-noise from their experiments, the fewest artifacts, and the best resolution. AutoCalibrate can be used for all users, no matter the types of samples they run. The parameters that are checked are global parameters used by nearly all NMR experiments,
- Pulse lengths– optimized for optimal signal with minimal artifacts
- Temperature– optimized for stability to reduce artifacts and shimming problems
- 3D Shimming– creates a daily base shim set (X, Y, and Z shims) to optimize resolution and reduce the amount of time spent on routine shimming (Z shims only).
- 量化– ensures qNMR integrity so users have confidence in the spectrometer calibration

The key ingredient to generating great NMR data
The aim of AutoCalibrate is to ensure all users are generating great data No matter if using TopSpin or IconNMR, be they beginner or expert spectroscopists.
Pulse Calibration
通过维持质子和碳脉冲长度, we ensure that the majority of all NMR data collected is acquired with the highest signal to noise and the least number of artifacts. Checking the pulse lengths is automated with AutoCalibrate, as is updating the pulse tables and generating update information in the form of a daily report. Go to bed and wake up to calibrated pulses! It couldn’t be any easier.
Temperature Calibration
Maintaining constant and accurate temperature will ensure stable chemical shifts and fewer artifacts in complex spectra. AutoCalibrate will set the proper flow rate, calibrate the heater power, and correct the temperature.
Shim Calibration
Creating a basis 3D shim plot for the AutoCalibrate standard sample enables faster and more accurate 1D shimming on user’s samples as well as troubleshooting information
量化
The AutoCalibrate sample contains a very accurate amount of DSS, 0.5mM specifically. Using this material, we can test qNMR response and calibrate against it for determination of accuracy.
Spezifikationen
Pulse Calibration
| Parameter | Behavior |
| Proton 90° Pulse |
Using the water signal, AutoCalibrate executes a 5-point array to determine the optimal 360° pulse and compares with 360° pulse expected from Prosol table.
|
| Carbon 90° Pulse | Using the DSS 13C satellites AutoCalibrate executes a 3-point array to determine the optimal 90° pulse and compares with 90° pulse expected from Prosol table.
|
Temperature
| Parameter | Behavior |
| Temperature 298K |
If measured temp deviates from 298K by >0.1K a new temperature correction curve is generated using measured start temp and then stat temp + 5K |
Shimming
| Parameter | Behavior |
| 3D shimming |
AutoCalibrate will run a 3D shim. It will save good shim file after testing linewidth to be certain shimming was successful.
|
qNMR
| Parameter | Behavior |
| qNMR test |
AutoCalibrate will use the PROF1H parameter set to measure the concentration of DSS and ensure it is 0.5mM. This can then be used with ERETIC II routine and the PROF1H parameter set to measure the concentration of unknowns.
