- PACKTEST is the most simplified analysis instrument for water quality check. Most of the PACKTEST utilize absorptiometry from corresponding Japanese official method (i.e. JIS K 0102) for its reaction principle.
- In other cases, like there is no absorptiometry set under the official method, meaning that there is no ideal reagent available with high sensitivity and selectivity of objective substance, so we came up with our own ingenuity utilizing to add masking and other technique.
