Forefront Online Protection for Exchange (FOPE) had a user interface separate from on-premises Exchange Server and Exchange Online. The new EOP user interface is identical in appearance with the Exchange Administration Center for on-premises customers, For Exchange Online customers, EOP features have been integrated directly.
A statistical method for computing practical quantitation limits (PQL) is developed. The PQL is operationally defined as the concentration at which the instrument response signal is 100/a times its standard deviation (e.g., for a 10% relative standard deviation (R.S.D.) a = 10). The response signal is defined as the ratio of analyte to internal standard peak areas.
QL is a component in binary chemical weapons, mainly VX nerve agent. It, along with Methylphosphonyl difluoride (DF), was developed during the 1980s in order to replace an aging stockpile of unitary chemical weapons. QL is listed as a Schedule One chemical by the Chemical Weapons Convention.
