Ask us anything: answers to 6 burning questions about the Echo® MS system
Experts Aaron Stella and Jacob McCabe from SCIEX answer 6 burning questions from customers about the Echo® MS system.
Standard peaks are noisy
I am Using Sciex Qtrap 4500 for quantification of nitrosamines (NDMA&NDBA). I am facing issue with higher baseline intensity. When developed the method in APCI the basline was at about 5e4. but now even after cleaning the source (i.e. Changed capillary to new, Curtain plate & Corona needle cleaning, given blank injection overnight ), my base line decreased from 1e6 to 4 e5, but settled at 4 e5 from past 24 hours. can you suggest me how decrease my baseline intensity further to below 1e5. My standard peaks are like noise now.
Loss the contact closure signal
our 7600 couple with nanoLC Ultimate 3000 via contact closure. it has run without any loss connection during the batch. Just yesterday, the last injection keep equilibrating system until the LC finished the gradient run. We closed the software and power off LC and MS then started again but it did not help. The Dionex engineer also checked their LC and triggerring cable found both are ok.
Easing the demands of a compliant pharmaceutical laboratory
At SCIEX, we are proud to provide analytical systems to the pharmaceutical industry. We work hard to understand the demands of analytical work and the processes required to develop and manufacture drugs.
General question on SCIEX 7500
Good morning.
Library database file types imported into LibraryView™
As is stated in official guidance, many different types of compound and library databases can be imported into LibraryView™ software, such as Excel file (*.xls) and Third Party Library Package (*.tplp). Can somebody tell me what's the format like "tplp", which is so...
Optimized rolling collision energy curves for IDA and SWATH DIA for peptides
During data dependent acquisition (DDA or IDA) or SWATH acquisition, the collision energy can be automatically adjusted according to the mass/charge and charge of the peptide. This dependency has been well characterized on our QTOF systems. By selecting rolling...
What has the Echo® MS system done for the pharma industry? (And don’t just take our word for it!)
SCIEX was very proud to have an illustration of the Acoustic Ejection Mass Spectrometry (AEMS) technology that powers the Echo® MS system on the front cover of the Journal of the American Society for Mass Spectrometry in January 2023. The associated article—Ultrahigh-Throughput Intact Protein Analysis with Acoustic Ejection Mass Spectrometry—was co-authored by scientists from SCIEX and Merck.
