The total dead time of a detection system is usually due to the contributions of the intrinsic dead time of the detector (for example the ion drift time in a gaseous ionization detector), of the analog front end (for example the shaping time of a spectroscopy amplifier) and of the data acquisition (the conversion time of the analog-to-digital converters and the readout and storage times).
The theory of high performance liquid chromatography-HPLC is, at its core, the same as general chromatography theory. [41] This theory has been used as the basis for system-suitability tests, as can be seen in the USP Pharmacopeia, [ 42 ] which are a set of quantitative criteria, which test the suitability of the HPLC system to the required ...
However, the possibility to record an EI spectrum from an HPLC application remained a challenge for a long time. The first Direct-EI prototype was first presented in 2002 [ 5 ] and proposed an innovative approach that improved interfacing performance compared to that of particle beam and opened new opportunities for LC-MS applications.

The time it takes for the solution to travel from the mixing point to the observation point is referred to as the "dead time." The minimum injection volume depends on the size of the mixing cell. Once enough solution has been injected to completely replace the previous one, the system reaches a stationary state, and the flow is stopped.
Mod packs are groups of mods put into one package for download, often with an auto-installer. A mod pack's purpose is to make it easier for the player to install and manage multiple mods. [73] Mod packs may be created with the purpose of making the original game more accessible to new players or to make the game harder for veterans to enjoy.
