Total Collaborative Study Protocol_Solus One Salmonella v1 1

MALDI Biotyper biochemical identification method, AOAC OMA 2017.09  (9). 

Comparison of the candidate Solus One  Salmonella and reference methods for all matrices indicated 

un‐inoculated test portions were all negative, high inoculation level test portions were all positive and 

fractional levels were achieved at the low inoculation level test portions using an automated sample 

preparation method.  

As per criteria outlined in Appendix J of the Official Methods of Analysis Manual, fractional positive 

results were obtained for each matrix (3). The POD analysis between the candidate Solus One 

Salmonella method and the FDA/BAM Ch. 5 reference method for all matrices indicated that there was 

no significant difference at the 5% level between the numbers of positive results by the two methods 

using an automated sample preparation method.  

The POD analysis between Solus One  Salmonella presumptive and confirmed results for all matrices 

indicated that there was no significant difference at the 5% level using an automated sample 

preparation method. A summary of POD analyses is presented in Tables 3 and 4.
