The article titled “Data-Driven Optimization of DIA Mass-Spectrometry by DO-MS” presents a new approach to optimizing data-independent acquisition (DIA) mass spectrometry. DO-MS uses a data-driven approach to fine-tune DIA methods and maximize peptide and protein identifications. DO-MS optimize parameters for DIA acquisition, leading to improved performance in terms of identification depth, accuracy, and reproducibility. The new approach could have significant implications for the field of proteomics, providing researchers with a powerful tool to improve the quality and efficiency of mass spectrometry-based proteomics experiments. The study utilized our 25cm Aurora Ultimate column for optimal coverage and sensitivity.

With over a decade of experience in proteomics research, I can confidently say that the IonOpticks column is the superior choice. Its exceptional analytical performance in terms of sensitivity and reproducibility has allowed me to maximize protein identification in any biological sample. Additionally, the column is robust and can withstand hundreds of runs without significant loss of performance. The customer service team is outstanding, always quick to respond to any questions or concerns. I highly recommend IonOpticks columns to any researcher seeking high-quality mass spectrometry data.

I have been using IonOpticks columns for 4 years, their performance is phenomenal, superior to any column I could pack myself, and they last at least 5 times as long. Switching to IonOpticks has saved me a huge amount of time, I simply do not have to stress about chromatography any more. The team are also responsive, and it is clear that customer satisfaction is important to them. Keep up the great work folks!

The Aurora columns are fantastic. Not only do they perform better than other columns on the market but they're durable and the single nano connection makes setup easy and simplifies troubleshooting. I use them for all my routine peptide and PTM applications.

We switched all our instruments with a 15 or 25cm aurora column for 1 year. Their performance, spray stability and robustness are really appreciated. We have really good results in label-free and DIA workflow compared to other columns used.

We obtained better results with IonOpticks...

 

We were able to leverage the very high accuracy of retention times as an additional feature to increase confidence in correct peptide identifications and to reduce confidence in incorrect ones.

We are very pleased with the performance of the Aurora column that can be applied to most proteomics studies. They allow us to acquire MS data with higher quality and especially improved in-depth proteomics output.

We have switched all our instruments from in-house packed 35cm emitters to Aurora columns. Their performance is equal or superior to our in-house packed columns, their spray-stability and durability is exceptional, they are fool-proof to install and last hundreds of runs.

We have recently started to use the Aurora columns and they significantly outperform any other columns that we have ever used for nano-LC-MSMS, by providing much higher peptide coverage in proteomics and phosphoprotemics.
