MS Lib Search Results

What do you want to do?

• Add MS compound from a library hit

• MS library search

• Compare MS spectrum against reference spectrum

The MS Lib Search Results window shows the results from the searched library.

NOTE

The MS Lib Search Results window is not visible by default. Open it via the ribbon.

NOTE

If your method expects a NIST library in a non-existing path (for example, C:\​NIST17\​MSSEARCH instead of C:\​NIST23\​MSSEARCH), the library search will return no results. In this case, add the libraries from the correct file path to your method.

Click the column header to sort its listed items in ascending or descending order.

Compound Name	Compound name for the matched spectrum in the MS library.
Match Score	NIST algorithm showing the matching between peak spectrum and library spectrum. For example, 878 can be read as 87.8 % match. The highest possible match score is 999.
Reverse Match Score	Similar to Match Score. The value is calculated ignoring all peaks in the sample spectrum that are not in the library spectrum.
Probability %	NIST algorithm; probability for the selected compound to be the correct one, considering all matched compounds in the libraries (up to 10).
Library Name	Name of the searched library.
CAS #	CAS registry number.
NIST #	NIST ID in the searched library. The values are specific to a compound and independent of the library.
Library ID	Compound ID in the searched library.
