A method measures a property of a solution spectroscopically by placing a quantity of the solution into a cuvette and passing a light therethrough. A reservoir receives a quantity of the solution and bubbles are driven off prior to putting a sample therefrom into the cuvette for measuring.一種藉由將一份溶液放到一比色器內並使一光線穿過的方式光譜地測量該溶液之一特質的方法。一貯器接收一份該溶液且在將一樣本從該貯器放到該比色器內以測量之前使氣泡被驅離。
