In-house spectral library creation to improve MALDI-TOF MS accuracy for microbial identification in pharmaceutical manufacturing

Key Points

• The primary aim is to enhance the accuracy of microbial identification using MALDI-TOF MS through a custom spectral library.
• Created an in-house spectral library for microbial identification using MALDI-TOF MS.
• Conducted a comparative analysis of identification accuracy before and after implementing the spectral library.
• Assessed performance in a controlled pharmaceutical manufacturing environment.
• Significantly improved identification accuracy from 75% to 90% post-library implementation, P<0.001.
• Reduced identification time by 30%, enhancing operational efficiency.
• Achieved consistent results across multiple microbial species tested.
