Abstract: A package of one or more absorbent articles is disclosed. The package includes a package material, wherein the package material has natural fibers and exhibits an MD tensile strength of at least 5.0 kN/m and an MD Stretch of at least 3 percent, each as determined via ISO 1924-3 as modified herein. The package further includes a plurality of panels, including a consumer-facing panel. The package is sealed.

Abstract: The present technology relates to a method of analyzing a sample including an analyte. The method includes injecting the sample including the analyte into a mobile phase. The mobile phase includes a metal chelator additive having a concentration between about 1 ppm to about 10 ppm. The method also includes separating the analyte using liquid chromatography and analyzing the analyte using a mass spectrometer, an ultra-violet detector, or a combination thereof.

Abstract: The present disclosure discusses a method of separating a sample (e.g., peptide compound) including coating a flow path of a chromatographic system; injecting the sample into the chromatographic system; flowing the sample through the chromatographic system; separating the sample; and analyzing the separated sample. In some examples, the coating applied to the surfaces defining the flow path is non-binding with respect to the sample—and the separated sample. Consequently, the sample does not bind to the low-binding surface of the coating (e.g., organosilica coating) of the flow path. The applied coating can reduce peak tailing and increase analyte recovery for the sample of the chromatographic system.
