Abstract: A quality control method or system for determining a lubricant coverage at the inside surface of a syringe barrel is provided. The timing for the quality control is not intuitive, yet crucial for patient's safety. The pre-fill test is for a pre-filled (empty or no drug solution), yet oil lubricated, barrel. This pre-fill test needs to be performed within a certain time window immediately following the lubrication. The post-fill test is for a post-filled oil lubricated syringe barrel filled with a solution. This post-fill test needs to be performed after a certain time window has passed from the filling with the solution. The quality control methods could lead to a reduction of health-risks or avoid life-threatening situations associated with syringes that are either below or above the desired lubrication coverage.

Abstract: A fast and fully automated approach for determining the number of atomic planes in layered material samples is provided. Examples of such materials may include graphene and bismuth telluride (Bi2Te3), and materials from the bismuth selenide (Bi2Se3) samples is provided. The disclosed procedure allows for in situ identification of the borders of the regions with the same number of atomic planes. The procedure is based on an image processing algorithm that employs micro-Raman calibration, light background subtraction, correction for lighting non-uniformity, and color and grayscale image processing on each pixel of a graphene image. The developed procedure may further provide a pseudo-color map that marks the single-layer and few-layer regions of the sample. Beneficially, embodiments of the developed procedure may be employed using various substrates and can be applied to materials that are mechanically exfoliated, chemically derived, or deposited on an industrial scale.
