Total Alkalinity:Samples for total alkalinity can be collected in borosilie glass or HDPE sample containers. Borosilie glass is preferable to "softer" glasses for sample storage. Storing samples in soda lime glass can cause significant increases in alkalinity concentrations as seawater can leach sodium and other compounds from the glass over time (Huang et al., 2012).
