Aromatics Calibration Standards Kit 4262-SET

1) 货号-4262-SET; 2) 英文名称: Aromatics Calibration Standards Kit 4262-SET; 3) 中文品名: 芳烃校准混标套装; 4) 描述: Aromatics Calibration Standards Kit(4 Internal Standard Version)24 Analytes + 4 ISTD, each Vol.% as listed in isooctane; units: 5x1 mL Set, one of each Std.1-5 + opt. 1x1 mL (Std. 6)To these calibration standards are 4 fluorinated Internal Standards added.ASTM D5769-98 recommends the use of a fourth internal standard. The use of an extra internalstandard with physical properties similar to toluene improves the analytical results fortoluene.Standard 6 of the calibration set is optional. It has been added in order to improve the linearityof the calibration curve. Use of the 6th standard provides an additional calibration pointthat is desirable when the calibration curve is developed using a quadric fit.S-4262 (Std. 1-5) S-4263Analyte Std. 1 Std. 2 Std. 3 Std. 4 Std. 5 Std. 6Vol.% Vol.% Vol.% Vol.% Vol.% Vol.%Benzene 3 1.50 0.75 0.375 0.1875 2.25Toluene 19 9.50 4.75 2.375 1.1875 15Ethylbenzene 5 2.50 1.25 0.625 0.3125 3.75m-Xylene 6 3.00 1.50 0.750 0.3750 4.50p-Xylene 6 3.00 1.50 0.750 0.3750 4.50o-Xylene 6 3.00 1.50 0.750 0.3750 4.50Isopropylbenzene 3 1.50 0.75 0.375 0.1875 2.25n-Propylbenzene 3 1.50 0.75 0.375 0.1875 2.251-Methyl-3-ethylbenzene 3 1.50 0.75 0.375 0.1875 2.251-Methyl-4-ethylbenzene 3 1.50 0.75 0.375 0.1875 2.251.3.5-Trimethylbenzene 3 1.50 0.75 0.375 0.1875 2.251-Methyl-2-ethylbenzene 3 1.50 0.75 0.375 0.1875 2.251.2.4-Trimethylbenzene 5 2.50 1.25 0.625 0.3125 3.751.2.3-Trimethylbenzene 3 1.50 0.75 0.375 0.1875 2.25Indan 3 1.50 0.75 0.375 0.1875 2.251.4-Diethylbenzene 3 1.50 0.75 0.375 0.1875 2.25n-Butylbenzene 3 1.50 0.75 0.375 0.1875 2.251.2-Diethylbenzene 3 1.50 0.75 0.375 0.1875 2.251.2.4.5-Tetramethylbenzene 2 1.00 0.50 0.250 0.1250 4.01.2.3.5-Tetramethylbenzene 2 1.00 0.50 0.250 0.1250 1.5Naphthalene 2 1.00 0.50 0.250 0.1250 1.5Pentamethylbenzene 2 1.00 0.50 0.250 0.1250 1.51-Methylnaphthalene 2 1.00 0.50 0.250 0.1250 1.52-Methylnaphthalene 2 1.00 0.50 0.250 0.1250 1.5; 5) 规格; 5x1ml 订购热线 400-811-9081 13681619662
