Quartz Gold Hyperbolic and Beautiful! Why quartz?Low coefficient of linear expansion (expansivity; ) dL = L0 dt [t = C; dL = change in length (m); L0 = length at 0 C] Why gold? Inert material with excellent electrical properties for high voltage Why hyperbolic? Ideal electrical field is generated by hyperbolic surfaces (NOT ROUND)Much more than just a beautiful piece of glass

5977A GC/MSD IDL SpecificationIDL is a statistically derived value from the precision (%RSD) of 8 consecutive, splitless injections of 100fg OFN at 99 % confidence level. The more precise instruments (lower %RSD) will generate lower IDLs.
The Agilent 7890B/5977A with an ALS or CTC autosampler has the following specifications:January 15, 201325Ion Source typeHigh Vacuum pump typeIDL of OFN by 8 replicates of ALS*Extractor SourceTurbo Pump10fg Inert SourceTurbo Pump24fgDiffusion Pump30fg*Systems without an Autosampler will have only S/N specification.These are installation specification, performed on customer site, immediately after installation and carry a lot more value than a reference specs. 25Why IDL specification is useful for the 5977 in SIM?Influence of Noise in S/N specs
In SIM (or MS/MS) when the Noise is too low, such as during acquisition of an OFN standard, S/N results may not give the best characterization
If the noise level is insignificant - varies a lot and too low- the derived value from it (S/N) also becomes insignificant
Value of IDL
IDL is derived from reproducibility/precision results, the same metrics most users utilize every day in their work. The IDL statistical process is the same used for Method Detection Limit calculations, and the %RSD values are tools to monitor analytical performance
IDL characterizes the whole system AS, GC, MS- giving confidence in overall reliability. It is the results of 8 consecutive injections, unlike S/N in a single shut, which can be influenced by many parameters/conditions
