The rising baseline at the end of the temperature ramp in GC/MS has a name: column bleed. We explain why it occurs and how Agilent J&W 5Q columns (DB-5Q and HP-5Q) minimize it by combining Ultra Low-Bleed and Ultra Inert technologies.

Choosing the right antibody is half the battle in a successful Western blot. We review host species, clonality, technical specifications, and the essential controls for validation.

Lithium-rich samples, high TDS, or aggressive digestions degrade the quartz in ICP-OES torches through devitrification in a matter of days. We explain the mechanism and how Agilent's ceramic outer tube increases lifespan tenfold compared to conventional quartz.
