Trace Analysis of Ox金地yhalides and Inorganic Anions 公機in Drinking Water Preserved with Ethy輛愛lenediamine 

Achieve high resolution 快窗separations of trace oxyhalides and 關制inorganic anions in drinki去還ng water using the Therm什就o Scientific^? Dionex^? IonPac^? AS27 hydroxide-selective anio那電n-exchange column. T舞會he selectivity of the Dionex IonPac 看美AS27 column has be女章en optimized for trace level analysis 畫的of bromate in t工討he presence of ppm levels of ethylen著劇ediamine (EDA). EDA is used as a pre員關servative in some d少路rinking water samples and can 師如cause interference of early eluting舊來 peaks, including br不明omate. The high resolut煙師ion, high capacity a坐也nd selectivity of the Dione討不x IonPac AS27 column allows the 區件determination of trace bromate in通話 drinking water without samp體鐘le pretreatment 河如or preconcentrati中懂on. The Dionex Ion物文Pac AS27 columns m是放eets the performance requi好好rements of US EPA Method技看s 300.0 and 300.1.

The Dionex IonPac AS27 column 知腦is available in three f高分ormats: 4 × 250 mm, 2不地 × 250 mm and 0.4 × 250 月黃mm.The Dionex IonPac A術理S27 Capillary Colu西有mn is packed with th銀秒e same material a購道s the equivalent standar場也d bore version (prov家村iding the same performan來雜ce as a 4 mm column), but req機白uires only 1/100th the eluent少空 flow rate.The capilla妹到ry format provides th身學e advantage of significan長呢tly reduced eluent consumption, which看們 helps reduce operati女木ng costs.

• Optimized for analysis of tr土樂ace bromate in drinking water preserved讀匠 with EDA

• High capacity: 220 μeq不呢 per column (4 × 250 看火mm)

• Meets or exceeds performance 嗎都requirements of US EPA Meth吃藍ods 300.0 and 300.1

• Column selectivity is optimized for山紅 30 °C operating temperature

• Compatible with organic solvents

The Dionex IonPac AS27 column i司這s designed for the analys友也is of oxyhalides and common i學雪norganic anions including fluori坐日de, chlorite, bromate, chloride, n開西itrite, bromide, chlorate, nit討但rate, phosphate, and sulfate in 分生drinking water, groundwater, wastew算月ater, and other diverse sample 購們matrices. The Dionex IonPac AS27 colu風黃mn allows analysis of most drinking w電資ater preserved with EDA without sample愛報 pretreatment or pre麗師concentration. This col志門umn is ideally used with an地美 RFIC system for automatic黑算 eluent generation.

The key applica妹那tion for the Di業秒onex IonPac AS27 column is the dete坐筆rmination of trace bromate in dri術開nking water matrices that have 師你been preserved with EDA using a pot業身assium hydroxide gradient with supp劇問ressed conductivity dete河慢ction. The selectivity 關動of the Dionex IonPac AS請林27 column ensures th制鄉at bromate can be quantified哥行 at low μg/L concentrati兒得ons using suppressed condu雪筆ctivity detection eve對資n in the presence of very high c師煙oncentrations o這商f chloride, sulf從技ate, and carbonat就哥e as well as EDA.

The Dionex IonPac AS27 column ha生件s similar selectivity and c離去apacity compared to the Dio討熱nex IonPac AS19 co裡跳lumn and most application算那s can be performed on ei你通ther column. Howe刀民ver, for samples preserved wit如火h EDA, the Dionex IonPa師訊c AS27 column is re影美commended.

The Dionex IonPac 少請AS27 column produc秒公es under 3000 psi at the standa山短rd flow rates and can b紅她e operated on any Di了紅onex IC system, such as the Th雜麗ermo Scientific^? Dionex^? ICS-5000⁺ HPIC^? or the Thermo Scientific Dionex ICS-400訊鄉0 Capillary HPIC syst睡謝em.
