The Deuterium ( D2 ) UV lamp disposal depends on the local regulations, which are different in every country. The D2 lamps (bulb is under vacuum) only contain a fairly small amount of Deuterium, which is not harmful. May be considered industrial waste…
Hello afzishle ,
I apologize for the delayed response.
It is possible to limit the number of results displayed in Report Builder tables or lists. You would sort by whatever you are evaluating your results by and then at the end of your filter use…
I'll just guess because you gave us very little information in my opinion.
But...It seems m/z 208 is shifted to more cc than it should. Maybe an interference with that m/z?
The 66x2mL tray has three white square plastic clips on its rear for automated identification by the sampler.
The 18x6mL tray just has one of the squares.
Please check your tray, i am pretty sure that some of these clips are missing.
You may will…
Okay, I just remembered - I didn't manage to change the size of the text in this program, it was in the Qualitative analysis program. So perhaps it is not possible to change the text size in this program. I really wish that feature would be added, for…
Hello Chalbrecht ,
I apologize for the delayed response.
There are a few options for naming the reporting output file using the sample or batch name with $(SampleName) and $(BatchFileName), but I don't see that the Sample Group is an option. You may…
Hello Achim_Hongenaert ,
I apologize for the delayed response.
There are a few outliers that can be used for recovery calculations. If this compound is added to all samples then I believe the best option will be to call it a Surrogate in quant, even…
Thank you, Linh, for your information. Given that it is an old machine, I am concerned about the potential loss of data if we upgrade the software. Instead, I will create a shutdown method to be executed at the end of the sequence run.
