First, the laboratory requirements
The laboratory area for placing the instrument is about 30 square meters (5m × 6m). The width of the laboratory should be more than 80cm. The room should be as dust-proof as possible (preferably double-layer doors and windows), the temperature is stable at around 25 °C, humidity Less than 65%.
1. The laboratory should install 2-3 cabinet air conditioners, and dehumidifiers should be installed in the south.
2. The laboratory layout is as follows:
3, computer workbench, equipped with a computer workbench with a length of 140 cm and a width of 70 cm and a swivel chair.
Second, the power requirements:
1. Instrument required voltage: single phase 230 VAC (+/-5%), 50~60Hz, instrument power consumption: 4.5KW, power insurance 30~32A (if required to install leakage protector, 300 mA leakage protector should be installed ).
2. Regulated power supply: In order to ensure the safe use of the instrument, it is required to be equipped with a single-phase 7.5K-10KW regulated power supply. The regulated power supply requires reliable quality, no harmonic interference, and has a purifying function. In addition, in order to prevent the sudden power failure and the power grid impact of the power transmission, a 30A AC contactor should be installed in front of the regulator. It is not possible to use a plug to connect to the mains before the regulator to prevent poor contact.
3, ground wire requirements: Spike's spectrometer requires the use of a dedicated ground wire, the ground resistance is less than 2Ω, as shown below:
First, dig three pits with a depth of one meter according to Figure 1 and Figure 2. The spacing between each pit is two meters. Then add 10 kg of salt water and grass ash to each pit, wait until the water has completely penetrated into the ground, and then in the pit. (According to Figure 1) Metal piles (steel rods: 3 cm in diameter, 120 cm in length, copper rods: 2 cm in diameter and 120 cm in length). Before hitting, the metal rods should be sanded and cleaned, the scale removed, and then used. A 4 mm copper wire is taken out of the ground and welded to the other two metal rods.
Third, ventilation requirements
In order to protect the environment and the health of the laboratory staff, the instrument room requires good ventilation. On the one hand, it contains various acid gases and a large amount of argon gas to be discharged outside, and the heat of the high-frequency generator can also be taken away to reduce The burden of the air conditioner. The centrifugal fan is used separately, and the air volume of the two air ducts connected to the instrument is independently adjustable. The ICP instrument and the air duct are connected by a metal high temperature (80 ° C) hose with a diameter of 100 mm, and the joint is used with a monkey. The hoop is stuck. Exhaust air volume requirements: The wind speed connected to the nozzle at the back of the instrument is 10 to 12 m / s, and the wind speed connected to the front nozzle is 4 to 6 m / s.
Fourth, argon
The working gas used in the ICP spectrometer is analytically pure argon (99.996%). Please prepare 5~7 bottles, or use liquid argon for installation and debugging. In addition, prepare an oxygen meter (double meter, small meter range 0-2.5Mpa, large scale range 0-25Mpa). If you want to make oil samples, you need to prepare a bottle of oxygen (99.99%), and an oxygen meter (double meter, small meter range 0-0.4Mpa, large scale range 0-25Mpa).
Five, steamed water
Since the ICP spectrometer is applied to trace analysis, it is necessary to use secondary quartz distilled water (ion exchange water and then distilled water from the quartz vessel twice) to reduce the blank.
6. Reagents and standard solutions
Prepare the appropriate reagents and standards according to the actual application.
Seven, instrument test bench
If the instrument test bench is not ordered at random, the user needs to prepare the test bench himself, as follows:
1, The load is more than 300 kg.
2, 700 mm high.
3, 800 mm wide.
4, It is 2000 mm long.
Eight, spectrometer calibration solution (need to be purchased by the user)
The spectrometer requires calibration of the optical system with the following mixed standard solutions: Â
element | Concentration (mg/L) | element | Concentration ( mg/L ) |
Ca | 1 | Eu | 10 |
Be | 2 | In | 10 |
Li | 2 | K | 10 |
Sr | 2 | Ni | 10 |
Mn | 5 | P | 10 |
Mo | 5 | Si | 10 |
Na | 5 | Ti | 10 |
Sc | 5 | V | 10 |
Ce | 10 | Y | 10 |
Cu | 10 | Zr | 10 |
Fe | 10 | S | 50 |
