Get the amount of mobile phases needed for a sequence. — get_phase

Given a dataframe containing the gradient steps, it calculates the amount of each phase needed for the sequence.

Usage

get_phase_amount(grad, ambient = 2, an = 1)

grad: a dataframe with 4 columns. The first column contains the minute of each gradient step. The second column is the flow in mL/min of each gradient step. The third column is the percentage of the A-phase at each step. The four column is the percentage of the B-phase at each step.
ambient: numeric of length 1. The number of minutes the system stays at the t0 conditions between each analysis.
an: numeric of length 1. The number of analyses in the sequence.

It prints the information on the console.
