2 cards from this section. Quick, good the night before a test.
What does TSS stand for?
It refers to the solids suspended in water.
Which instrument is primarily used for gravimetric measurement?
Think of a device that weighs items.
What is gravimetric measurement primarily used for?
Think about what you need to find concentration.
True or False: The detection limit of an instrument affects the reliability of gravimetric measurements.
What happens if the instrument cannot detect small masses?
You have a sample of water from a river known to have low TSS levels. The balance used to measure the TSS has a detection limit of 0.5 mg. Given that the water sample is only 0.2 mg of TSS when measured, what can you deduce about the accuracy of your measurement?
Think about how detection limits affect what you can conclude from your findings.
A researcher finds that different samples taken from the same lake at different times yielded varying TSS results. What factors could contribute to this variability?
Consider dynamics in natural environments that can cause fluctuation in water samples.
