GL Sciences 106B Instruction Manual

★ READ CAREFULLY THIS INSTRUCTION MANUAL AND THE INSTRUCTIONS OF THE
ASPIRATING PUMP PRIOR TO USING THIS PRODUCT.
★ DO NOT DISCARD THIS INSTRUCTION MANUAL UNTIL ALL THE TUBES IN THIS BOX ARE
USED UP.

Aspirating Pump
1. THE DETECTOR TUBE CONTAINS CHEMICAL REAGENTS.
2. DO NOT TOUCH THESE REAGENTS DIRECTLY ONCE TUBES WERE BROKEN.
3. KEEP THE TUBES OUT OF THE REACH OF CHILDREN.
NOTICE
1. USE ONLY WITH PUMP MODELS AP-20, AP-20S, 400B, AP-1, AP-1S OR 400A.
OTHERWISE, CONSIDERABLE ERROR IN INDICATION MAY OCCUR.
2. BEFORE TESTING, CHECK THE ASPIRATING PUMP FOR LEAKS (REFER TO ITEM 8.
INSPECTION OF ASPIRATING PUMP). ANY PUMPS SHOWING SIGNS OF LEAKAGE
SHOULD BE CORRECTED BEFORE USE.
3. DO NOT USE THIS TUBE OUTSIDE THE STATED OPERATING TEMPERATURE RANGE.
4. STORE TUBES IN A COOL AND DARK PLACE (0-25 ℃/32-77°F), AND USE BEFORE
EXPIRATION DATE PRINTED ON THE TOP OF THE BOX.
5. PRIOR TO USE, READ CAREFULLY ITEM 9. USER RESPONSIBILITY.
6. READ THE CONCENTRATION IMMEDIATELY AFTER MEASUREMENT.
2. SAMPLING AND MEASUREMENT:
※ Reagent of 1st layer is for removing the coxistence gas such as Ethylene. 2nd layer is for reading the
concentration.
① Break both ends of the detector tube.
CAUTION SAFETY GLASSES AND GLOVES SHOULD BE WORN TO PREVENT INJURY
FROM SPLINTERING GLASS.
② Insert the end of the detector tube marked with red dot into the aspirating pump securely as shown in Fig.1.
③ Align the guide marks on the shaft and stopper of the aspirating pump.
④ Pull the pump handle at a full stroke until it locks and wait for 30 secconds
CAUTION THE SAMPLING TIME SHOULD BE COUNTED PRECISELY FROM THE TIME
WHEN THE PUMP HANDLE WAS PULLED.
⑤ Remove the detector tube from the pump and wait for 2 minutes to change the colour of reagent at 15 ℃.
※ Waiting time depend on the temperature of detector tube and sampling time. REFER TO TABLE OF
WAITING TIME.
⑥ Read a concentration to compare the colour stain of the 2nd layer reagent with a color standard chart.
⑦ When the concentration is below the 100ppm, sampling time of 1 ～ 5 minutes can be used to determine
concentrations of 10 to 100 ppm. At this point, turn the handle right or left by 1/4 (90
without removing the detector tube from the pump and repeat the steps ③～④ for further sampling time.
⑧ On completion of sampling and waiting, correct the chart reading with the following equation to obtain a true
concentration.
