Response to Different Methods of Suspended Sediment Sample Storage Before the Coulter Multisizer Analysis: I. Inorganic Matter

This article details the variations with time of the size spectrum of inorganic marine particle samples stored according to three different methods: storage with formaldehyde; within a darkened and cooled (4°C) incubator; and by freezing. In view of the lack of a pretreatment with the ultrasonic bath, freezing represented the only method apt to keeping the spectrum unvaried with time. Given the use of ultrasonic bath pretreatment, all three storage methods become applicable.
