    Pharmaceutical liquid products such as syrups, mixtures, and solutions are used for treating patients who find it difficult to swallow easily the tablets and gel capsules.

    The type of liquid helps in deciding which type of color measuring instrument should be used for color measurement of that liquid. Here are some indications.

    Opaque liquids

    Opaque liquids are the ones that do not allow the light to pass through them. It would be best to use a reflectance type color measuring instrument with a 450/00 viewing angle.

    Translucent liquids

    For translucent liquids, different degree of translucency will need a different type of color measuring solution. For translucent liquids, both the transmittance and reflectance type instrument will work according to the extent of translucency exhibited by the test sample.

    Transparent Liquids

    The transparent liquids are the ones that allow the light to pass through them with very little or no interruptions. For such types of liquids, only transmittance type instrument should be used for best assessment of color quality.
