“…3 These solid packed reactors (SPRs) employ different fillings and different alternatives for packaging. [4][5][6][7][8][9][10] In the particular case of analytical reagents able to be employed in solid phases or in suitable solutions, 9 the former choice has been reported to be advantageous for favoring the degree of mixing, mainly when single-line configurations are employed. 10 Nevertheless, problems related to the amount of reagent released by the column and the clogging of the FI systems must be solved.…”

“…[4][5][6][7][8][9][10] In the particular case of analytical reagents able to be employed in solid phases or in suitable solutions, 9 the former choice has been reported to be advantageous for favoring the degree of mixing, mainly when single-line configurations are employed. 10 Nevertheless, problems related to the amount of reagent released by the column and the clogging of the FI systems must be solved. For the first case, a compromise between the reagent solubility and the reactor lifetime needs to be attained: highly insoluble reagents increase the reactor lifetime but its supply to the carrier may not be good and highly soluble compounds may be quickly exhausted.…”

“…For this task, a diode array spectrophotometer [1], or a single instrument in association with di erent strategies, e.g. stream splitting [2], closed-loop con® guration [3], sandwich techniques [4,5],¯ow reversal [6], oscillating streams [7], parallel streams towards the instrument optical beam [1], etc. have been used.…”
