Higher Resolution of 紅綠Trace Oxyhalides and Inorg科懂anic Anions in 工照Complex Matrices using Smalle物少r Particle Columns

Achieve high resol吃電ution separations of trace oxyh離書alides and inorganic明什 anions in drinking water us個看ing the Dionex IonPac AS19-4μm 頻睡hydroxide-selective低學 anion-exchange colu北喝mn. Its high resolution, high capacity 厭藍and selectivity allow the determ時吧ination of bromate in drinking water a見白t the low-μg/L level. Compared to th是能e previous Dion微離ex IonPac AS19 column, th事志e new anion-exchange column use討少s smaller resin particles for more ef笑光ficient separations resulting in mor城去e accurate peak integration and 冷些more reliable results. It作日 has similar selectivity and increa訊個sed peak efficiencies廠線 compared to the Dionex文短 IonPac AS19 column, ens家器uring that applica姐信tions run on the Dionex IonPac AS歌門19 can be easily t裡家ransferred to the Dionex友草 IonPac AS19-4μm column. The Dionex東請 IonPac AS19-4μm columns meet舞月s the performance requirements of 錢術US EPA Methods 3相有00.0 and 300.1.

The Dionex IonPac 森兒AS19-4μm column is ava紙綠ilable in three formats: 4 們水× 250 mm, 2 × 250 mm鐵我 and 0.4 × 250 mm.The Dionex IonP高件ac AS19-4μm Capillary 器黑Column is packed with the 知房same material as the equi員歌valent standard bore version (prov自海iding the same performance as我雨 a 4 mm column), 拍站but requires only 1/100th the eluent f金銀low rate.The capillary通就 format provides the advantage of s科票ignificantly reduced eluent訊一 consumption, which hel外鐵ps reduce operatin一但g costs.

• Recommended hydroxide-selective c著筆olumn for trace bromate in drink她制ing water matrices

• High capacity: 哥刀240 μeq per column (4物空 × 250 mm)

• Meets or exceeds pe子要rformance requirements of US暗煙 EPA Methods 300.靜器0 and 300.1

• Column selectivity is optimized for 30吃金 °C operating temperat喝你ure

• Compatible with o笑還rganic solvents

• High-pressure T報唱hermo Scientific Dionex ICS-5000⁺ or Dionex ICS-4000 HPIC system is 快資required to run at standard flow行外 rates.

The Dionex IonPac AS19煙問-4μm column is des樂也igned for the analysis of oxyhali務有des and common inorganic anion樂光s including fluoride, ch商志lorite, bromate, chlor水器ide, nitrite, brom制動ide, chlorate, nit厭志rate, phosphate, and紅很 sulfate in drinking wat那可er, groundwater, wastewater, and鄉件 other diverse sample ma是他trices. The Dionex IonPac A睡低S19-4μm column allows analysis of most 朋門drinking water without the us森上e of sample pretrea朋弟tment or preconcentration. This c說黃olumn is ideally used 自物with an RFIC system for automati雪坐c eluent generation.城店

The key application for t師和he Dionex IonPac AS19-4μm c大少olumn is the dete吧志rmination of trace bromate in dri高做nking water matrices using a 笑老potassium hydroxide gra嗎海dient with suppressed conductiv子土ity detection.
