    Technical/Application Article 02 Version 1.10 22nd January 2018 WRH/FD Ion Science PID Response Factors PID Response Photoionisation Detectors (PIDs) respond to a broad range of organic and a few inorganic gaseous and volatile chemicals (‘volatiles’). In order for PID to respond to a volatile, the photon energy of the lamp must be greater than its ionisation energy (IE). Ion Science PIDs are available with lamps emitting light of maximum energy of 10.0 eV, 10.6 eV, and 11.7 eV. This Technical Article lists the response factors (‘RF’s’) for over 900 volatiles with PID incorporating these lamps. The RF relates the sensitivity of PID to a volatile to the sensitivity to the standard calibration gas isobutylene. The higher the RF, the lower the sensitivity. Isobutylene as Reference Gas Ideally, the PID response to a chemical volatile would be calibrated by using a low concentration of the chemical in air. However, this is often not practical. Isobutylene is then used to calibrate PID, and a Response Factor (RF) used to convert the isobutylene calibrated measurement to a measurement of the target volatile: Concentration of target chemical = isobutylene calibrated measurement x RF For example, the RF of anisole is 0.59 with a 10.6 eV lamp. Therefore, a reading of 10 ppm using an isobutylene-calibrated unit would indicate: Concentration of anisole = 10 ppm x 0.59 = 5.9 ppm In Ion Science detectors, RFs are pre-programmed into a compound library and can be called up to make the PID read out in units of the chemical of interest.

Blum ABSTRACT The conductivity and density of chromic acid solutions were determined (<*r concentrations to molar up 10 (1,000 g/1 of Cr03 ). The density is practically a linear function of concentration. The conductivity increases to a maximum at about 5 molar and then decreases. CONTENTS Page I. Introduction 255 II.

INTRODUCTION This study is a step in an investigation of the theory of chromium plating. The solutions used in this process have chromic acid as their principal constituent. In addition, they contain some other anion, such as the sulphate ion, which is introduced as sulphuric acid or as a sulphate. During operation there is always formed in the bath some trivalent chromium, commonly supposed to exist as "chromium chromates" of undefined composition. The ultimate purpose of this research is to determine the form and function of the sulphate and trivalent chromium in such solutions. The effects of these constituents upon the density and conductivity of chromic acid will they throw light on this problem. ; be measured to see whether First, however, it was necessary to determine the density and con- ductivity of pure chromic-acid solutions to serve as a basis of refer- ence.

  • Reactions of Alcohols

    Reactions of Alcohols

    Reactions of Alcohols Alcohols are versatile organic compounds since they undergo a wide variety of transformations – the majority of which are either oxidation or reduction type reactions. Normally: Oxidation is a loss of electrons; Reduction is a gain of electrons. But in organic terms: Oxidation: loss of H2; addition of O or O2; addition of X2 (halogens). Reduction: - addition of H2 or H ; loss of O or O2; loss of X2. Neither an oxidation nor reduction: Addition or loss of H+, H2O, HX. Ch11 Reacns of Alcohols (landscape).docx Page 1 Oxidation of Alcohols Primary and secondary alcohols are easily oxidized by a variety of reagents. Secondary Alcohols The most common reagent used for oxidation of secondary alcohols to ketones is chromic acid, H2CrO4. Chromic acid is produced in situ by reaction of sodium dichromate, sulfuric acid and water. Na2Cr2O7 + H2O + 2H2SO4 2 H2CrO4 + 2 NaHSO4 Ch11 Reacns of Alcohols (landscape).docx Page 2 Mechanism of oxidation The alcohol and chromic acid produce a chromate ester, which then reductively eliminates the Cr species. The Cr is reduced (VI IV), the alcohol is oxidized. Oxidation of Primary Alcohols Primary alcohols are easily oxidized just like secondary alcohols, and the INITIAL product of oxidation is an aldehyde. Ch11 Reacns of Alcohols (landscape).docx Page 3 However, the aldehyde can also be easily oxidized to an acid, and this ‘over-oxidation’ is a practical problem. E.g. A common reagent that selectively oxidizes a primary alcohol to an aldehyde (and no further) is pyridinium chlorochromate, PCC. N: CrO3, HCl (PCC) E.g. Tertiary Alcohols These are resistant to oxidation because they have no hydrogen atoms attached to the oxygen bearing carbon (carbinol carbon).
