Halogenated acetic acid in drinking water
Samples are filtered by sand core filter. Using CIC-D120 ion chromatograph, SH-AC-3 anion chromatographic column, 2.4mM Na2CO3/3.6mM NaHCO3 eluent and bipolar pulse conductance method,under the recommended chromatographic conditions,the chromatogram is as follows. ...Read more -
Mineral water
The mineral water is a kind of water which is spontaneously gushing from the deep underground or collected by drilling and contains a certain amount of minerals, trace elements or other components and is not polluted in a certain area and takes preventive measures to pre...Read more -
Drinking water analysis
Water is the source of life. We must make all people satisfied (adequate, safe and easy to get) water supply. Improving access to safe drinking water can bring tangible benefits to public health, and every effort should be made to ensure the safe use of drinking water. T...Read more -
Bromate in mineral water
Bromate is a kind of strong carcinogenic substance，which is the byproduct of disinfect treatment using ozone. It is a necessary inspection item fmineral waters production. Using CIC-D120 ion chromatograph, SH-AC-11 Column and 15.0 mM NaOH eluent, the chromatogram is a...Read more -
Oil analysis
Based on the flammability of petroleum, chlorine, nitrogen and sulfur in petroleum products are converted into hydrides and oxides at high temperature by combustion furnace, then absorbed by alkali liquor . Using CIC-D120 ion chromatograph, SH-AC-3 anion column, 3.6 mM N...Read more -
Oil field waste water
Choosing appropriate dilution ratio to dilute oil field waste water, the diluent was filtered by 0.22 um microporous membrane and treated by IC-RP column.If the sample contains heavy metal and transition metal ions, it must be treated by IC-Na column . Using CIC-D120 ion...Read more -
Mud logging
During drilling, the recirculation and addition of drilling fluid will inevitably interact with stratum fluids and cause continuous chemical changes, which will change drilling fluid properties and lead to changes in ion species and concentration of drilling fluid filtra...Read more -
Atmospheric particles
The environmental samples of a certain volume or time are collected according to the sampling requirements of TSP, PM10, natural dust and dust storms in the atmosphere. A quarter of the filter membrane samples collected are accurately cut into plastic bottles,adding 20mL...Read more -
Surface water
Surface water is generally relatively clean. After 30 minutes of natural precipitation, taking the non precipitation part of the upper layer for analysis. If there are many suspended substances in the water sample or the color is darker, pretreat it by centrifugation, fi...Read more -
Environmental analysis
F-, Cl-, NO2-, SO42-, Na+, K+, NH4+, Mg2+, Ca2+, etc. are the necessary items to be detected in the study of atmospheric quality and rainfall. Ion chromatography (IC) is the most suitable method for the analysis of these ionic substances. Atmospheric gas sample:Gener...Read more
