On the Calibration of Cascade Impactors
From Abstract: "In the following paper, the two customary methods of calibrating cascade impactors are compared. It is shown that the method of determining collection efficiency as a function of particle size for each stage provides information for interpreting results in terms of impactor theory, making it possible to establish adequate jet performance."

A Cascade Impactor Operating at Low Volumetric Flow Rates
Report describing a five-stage cascade impactor, which has four impactor stages in which round jets are used and a filter stage. The method of calibrating the device is described. The significance of the collection efficiency and wall losses with respect to sampling for mass distributions is discussed.

Ultramicro Methods in Biochemistry: [Part] 1. General Consideration, [Part] 2. Procedures for the Determination of Serum Bilirubin
From Introduction: "The purpose of this paper is first to present a positive, but initial, approach that has been taken to meet these requirements, and second to report in detail the ultramicro method developed and evaluated for determining serum bilirubin. Subsequent publications will set forth the techniques finalized for other biochemical constituents."
