PACK TEST



적용분야
배수검사, 공정검사

기능
발색시약이 들어있는 비닐튜브에 물샘플을 넣고, 지정시간이 지난 후 표준색과 비교하는 방법으로 수질을 검사하는 쉽고 편리한 수질 검사용 팩입니다.PH조정등 비색적정에 필요한 전처리 과정을 최대한 줄여 누구라도 쉽게 측정할 수 있도록 고안하였습니다.측정결과를 5분안에 알수 있습니다.(일부항목제외),분석용 시험지에 비해 좀더 낮은 농도까지 측정할 수 있다.

Range:0.5, 1, 3, 5, 10mg/l

Reaction Time:2min

Method:DDTC

Quatity(pcs/box):50test

 

Cautions

1. The Copper PACK TEST allows to measure dissolved Cu2+ ion fraction. If you wish to measure

total copper fraction including suspended particles, you must process samples in order to

dissolve solid phases.

2. The normal pH range is 5 - 9. If necessary, adjust the pH with diluted sulfuric acid or sodium

hydroxide solution.

3. Ensure that PACK TEST tube is filled up to the half.

4. Partially undissolved reagent will not affect the measurement.

5. Keep sample temperature in the range 15°C - 40°C. Lower temperature necessitates longer

reaction time.

6. Read the test under a daylight type lamp.

7. Put the line back into the aperture after use to prevent reagent spilt.

 

Interferences

Standard colors were determined from standard solutions. However, coexisting ions can modify

reaction color. The list below reports ion concentrations under which ones interferences are

insignificant:

≤ 1000 mg/L : Al3＋, As3＋, B3＋, Ba2＋, Ca2＋, Cd2＋, Cl－, F－, I－, K＋, Mg2＋, Mn2＋, Na＋, NH4

＋, NO2

－,

NO3

－, Pb2＋, PO4

3－, SO4

2－, Zn2＋, Phenol

≤ 250 mg/L : Residual chlorine

≤ 50 mg/L : Co2＋, Cr3＋, Fe2＋, Fe3＋, Sn2＋

≤ 25 mg/L : Ag＋

≤ 10 mg/L : Ni2＋

≤ 5 mg/L : CN－, Cr6＋

The Copper (DDTC) PACK TEST is suitable for sea water samples.
