The inherent problem with this is that acquiring all of them at commercial rates can be prohibitively expensive. With this in mind, we have created a low-cost alternative to the most commonly used peptide calibrants. We were able to achieve an overall 78 ppm mass accuracy across a mass range of 900 to 2500 Da which was comparable to the mass accuracy achievable with commercial peptide mixes and hence has become a viable alternative.
