Automated system for detection of silicon species in phosphoric acid

A silicon speciation system for analysis of a fluid sample, comprising:

• a first valve having a first valve configuration to receive a remote sample containing phosphoric acid from a remote sampling system into a holding line coupled to the first valve;
• a pump assembly fluidically coupled to the first valve, the pump assembly including one or more pumps fluidically coupled with the first valve in a second valve configuration to deliver the remote sample or a diluted remote sample from the first valve;
• a second valve fluidically coupled to the first valve, the second valve coupled with each of an analysis output line and a silicon speciation portion having a speciation column, the second valve having a first valve configuration that fluidically couples the first valve with the silicon speciation portion to separate one or more species of silicon in the remote sample or the diluted remote sample via the speciation column, the silicon speciation portion coupled with the analysis output line and further including an eluent pump configured to direct an eluent through the speciation column to transfer the one or more species of silicon to the analysis output line, the second valve having a second valve configuration that fluidically couples the first valve with the analysis output line and bypasses the silicon speciation system.
