Installation
For the ATP Tests you will need the following samples
The three Test Samples which were shipped with the system.
• 3% CDCl3 in Chloroform (lineshape)
• 0.1% EB in CDCl3 (1H SINO)
• ASTM (C13 SINO)
To shim the magnet and perform the ATPs test you will require to bring some additional
samples:
• Urea in DMSO (Pulse Length adjustment)
• 100mg or 1g Cholac in CDCl3 (DEPT)
• Cyclosporine in C6D6 (2D Examples)
There are only three hard specs for the Fourier required for a customer sign off:
The remaining ATP Tests will implicitly demonstrate the system remaining functions:
• Water Supression
• Sample Spin & Lift
• Auto-Locking on various solvents
• Gradient Functionality (2Ds & Gradshim)
• Gradshim reproducibility
• Lock and Temperature Stability (COSY & HSCQ)
• * Baseline & Spectral Purity (DEPT)
* Certain Artefacts are normal and have been considered acceptable for the
intended use of the Fourier:
• A moderate amount of T1 noise in 2D experiments
• Some "digital noise" on strong signals that require RG < 10. Use zg30 instead zg of
if that happens, in order to be able to increase RG
• Some vibration noise close to the feet of very narrow lines (e.g. lineshape samples).
This can be improved with vibration damping if required.
• * Some very small spurious spikes in the first few scans of C13 spectra. These
should average out after NS > 64
Lineshape using 3% CDCl3 in Acetone 0.5/8/16 Hz (non-spinning)
1H Sensitivity (0.1% EB in CDCL3) 125:1 (after gradshim)
C13 Sensitivity (ASTM) 90:1 (after gradshim)
