AV500 : WORKING NORMALLY
Few of the users have noticed a spike ridden baseline in the past several days, mostly in 1H spectra, apparently. Evidently this is a sporadic issue since not all of them have reported this. As I speak, the spectrometer is giving clean 1H spectrum, as shown below :
Multiple causes can account for the observed spikes, that include instability in the room temperature or a circuit board sporadically overheating. If it is similar to the latter, we have to wait till the issue ‘precipitates’ before we can identify the part responsible and repair it.
I will keep you posted of further observations.
