A magnetic bead reagent contains: a magnetic bead containing a Fe-based metal soft magnetic particle and a silica film that has an average thickness of 20 nm or more and that covers the Fe-based metal soft magnetic particle; a surfactant; and a dispersion medium in which the magnetic bead is dispersed. The surfactant may be a nonionic surfactant.

A dispensing device that dispenses a liquid sample with a target weight x (in grams) includes: a pipette that discharges the liquid sample into a vessel; and a controller that controls the pipette. The controller performs: first liquid discharge processing in which the controller discharges the liquid sample with a volume of (x/ρ0×y) milliliters (mL) into the pipette, where y is a numeric value greater than 0 and smaller than 1, and ρ0 is the tentative density (in grams per mL) of the liquid sample; first weight acquisition processing in which the controller acquires information about the weight z (in grams) of the liquid sample discharged in first liquid discharge processing; density calculation processing in which the controller calculates the density p (in grams/mL) of the liquid sample according to the expression ρ=z/(x/ρ0×y); and second liquid discharge processing in which the controller discharges, into the pipette, the liquid sample with a volume based on the density ρ, weight z, and target weight x.

Dispensing device and dispensing method

A composition for aqueous ink contains water and a coloring material, wherein the calcium ion content x (ppm) and the oxalate ion content y (ppm) in the composition for aqueous ink jet satisfy the relation of y≤3491.8x.

Composition for aqueous ink jet and method for producing recorded product

A composition for aqueous ink jet contains a specific dye which is one or more coloring materials selected from the group consisting of C. I. Acid Black 172 and C. I. Acid Black 194, and a specific aromatic compound which is at least one compound selected from the group consisting of compounds represented by formulae (1) to (4) below. The content of the specific aromatic compound relative to 100 parts by mass of the specific dye is 0.2 parts by mass or more and 50 parts by mass or less.

Composition for aqueous ink jet

An ink jet textile printing ink contains 5% by mass to 20% by mass of a water-soluble dye, water, a water-soluble organic solvent, and active carbon particles. The active carbon particles include particles having a particle size of 50 nm to 1000 nm, and the active carbon particles having the particle size of 50 nm to 1000 nm are contained in a proportion of 500 to 300000 particles per milliliter. Also, the active carbon particles may include particles having a particle size of 50 nm to 200 nm, and the active carbon particles having a particle size of 50 nm to 200 nm may be contained in a proportion of 2000 to 30000 particles per milliliter. The active carbon particles may have an average particle size in the range of 100 nm to 600 nm.
