Abstract: The present disclosure discusses a method of separating a sample of tyrosine kinase inhibitors or metabolites of tyrosine kinase inhibitors which includes injecting the sample into the chromatographic system having one or more low-bind coated surfaces along the flow path; flowing the sample through the chromatographic system; separating the sample; and analyzing the separated sample. Consequently, the sample does not bind to the low-binding surface coatings (e.g., alkylsilyl coatings) of the flow path. The applied coating can reduce peak tailing and decrease carryover for tyrosine kinase inhibitor samples during chromatographic analysis.

Abstract: An isolated industrial float assembly is sized to fit interior to an existing gauge pole to signal a fluid level to an observer while preventing or lowering emissions from volatilization of fluids from the gauge pole. The isolated industrial float assembly includes a positively buoyant core manufactured from hydrocarbon resistant foam sealed within a shell. End caps enclose the shell. A vertical member secures the end caps tautly in position by connection with fasteners. Assembly and disassembly of the float assembly is enabled to replace parts as needed. The buoyancy of the core is sufficient to cause the float assembly to maintain position at the fluid-atmosphere interface, even in embodiments where the shell is fabricated of stainless steel.
