Abstract: The analysis device is provided with multiple reference samples which differ in transmittance and color, a storage unit which stores the brightness values, and a control value of the light source. The control unit irradiates the reference sample with light at a set control value, and stores an acquired measured brightness value of the reference sample, and an adjustment control value of the light source for adjusting to a set reference brightness value; from the brightness value of a sample to be measured, which was acquired by irradiating the sample to be measured with light on the basis of the control value, the control unit calculates an adjustment control value of the light source on the basis of the relation between the adjustment control value of the light source and the brightness value of the sample to be measured, and uses the adjustment control value to irradiate light.

Abstract: A molded pulp article that has a high strength and allows drying during production to be completed in a short time, having a percentage of fibers having a fiber length of 1 mm or less in pulp is in the range of 15% to 35%, the pulp has an average fiber length in the range of 1.5 mm to 2.5 mm, the molded pulp article has a nitrogen content in the range of 200 ?g/g to 1800 ?g/g, and the molded pulp article has a thickness in the range of 0.8 mm to 2.0 mm.

Abstract: A molded pulp article that has a small thickness and high strength and is excellent in release properties at the time of production, comprising a percentage of fibers having a fiber length of 1 mm or less to pulp is in the range of 35% to 50%, the pulp has an average fiber length in the range of 1.2 mm to 1.5 mm, the molded pulp article has a density is in the range of 0.65 g/cm3 to 1.3 g/cm3, and the molded pulp article has a nitrogen content is in the range of 400 ?g/g to 2000 ?g/g.

Abstract: A pulp molded product includes a surface that has a region with an arithmetic average roughness Ra of 50 ?m or less. A method of producing a pulp molded product includes: preparing a slurry that contains pulp having an average fiber length of less than 3.0 mm and water; depositing the pulp on a paper-making mold having a solid shape to form a pulp layer; dehydrating the pulp layer to obtain an undried intermediate molded product; and heating the undried intermediate molded product while sandwiching the intermediate molded product between a male mold and a female mold and applying pressure to the sandwiched intermediate molded product.

Abstract: The object of the present invention is to prepare purified erythromycin by removing erythromycin F from erythromycin. The present invention provides a method for preparing purified erythromycin from which erythromycin F is removed, which comprises the step of extracting erythromycin F from erythromycin using (i) an organic solvent and (ii) water or an aqueous solution of an inorganic and/or organic material.
