Utilising the Component Approach 2011 Waters Corporation 6
What are components? Components are a way of simplifying and organising complex data into groups which relate to the same chemical entity Each component contains a wealth of analytical information: Mass, retention time, isotopic, fragments (MS E ), adducts, drift time, multiply charged, multimers and more. Components can be utilised for: Targeted analysis Non / semi-targeted analysis 2011 Waters Corporation 7
Peak Detection Algorithm Standardised on the Apex Peak detection algorithm How does it work? An 2Identify Compute nd real ideal Derivative peak -parameter centroid Find apex The same routine is applied in all available dimensions Peak detection will utilise all available CPUs GPU 2011 Waters Corporation 8

Targeted Analysis 2011 Waters Corporation 11
Building the Questions When screening for a target the analyst is asking Does the data contain Compound X? With information from the UNIFI Scientific Library we can translate this in to: Can we find the precursor? o C 11 H 13 NO 4 o FW : 223.2252 Does the sample contain Compound X? At a retention time of 2.31 minutes? Can we find any confirmatory fragment information? o C 9 H 10 O 3 o FW : 166.1739 This can be expanded to include any other confirmatory conditions: Is there any isotopic evidence to confirm this identification? Can we compare against a library spectrum? 2011 Waters Corporation 12
Building the Questions When screening for a target the analyst is asking? Does the data contain Compound X? This can be expressed as a series of simple building blocks: Precursor Formula C 11 H 12 NO 4 and Retention Time 2.31 minutes and MS E Fragment C 9 H 10 O 3 with Isotopic Match Observed vs Theoretical Created to provide the maximum confidence in the identification of the target Can be run within a method or ad-hoc 2011 Waters Corporation 13

Target the unknown of interest Ad-hoc Analysis The examples so far have described a method based approach, but since we have the components we can ask questions in an ad-hoc fashion. For example: Which components contain chlorine? Which components contain an alkene loss? Or we could ask Which components contain chlorine AND an alkene loss? Components Data Ad-hoc Chlorine Filter (isotopic info) AND Alkane Filter (loss of 28) Filtered Components 2011 Waters Corporation 22
