Left: Peak shapes of earlier eluting peaks with a 5 ?L injection and 20 ?L plugs of mobile phase A surrounding the sample volume. Right: Peak shape improvement of earlier eluting peaks with an 8 ?L injection and 38 ?L plugs of mobile phase A surrounding the sample.

Figure 9 compares the response between the SRM method derived from experimentally optimizing via a classic infusion experiment and SRMs imported from mzCloud. A very high correlation is observed between the two methods, in terms of product ions selected, CEs, and the intensity of SRMs. Importing from mzCloud can dramatically decrease method development times, and methods can even be developed when analytical standards are not available or prohibitively costly.
