简介:5.1 This technique is designed for on-site rapid screening and characterization of environmental soil and water samples resulting in significant cost savings for environmental remediation projects. Remote analysis can be made with optical fibers when situations warrant or demand use of this option. 5.2 Quantification of total AHs and PAHs in these environmental samples is accomplished by having a subset of the samples analyzed by an alternate technique and generating a site-specific calibration curve. 5.3 Synchronous fluorescence provides sufficient spectral information to characterize the AHs and PAHs present as benzene, toluene, ethylbenzene and xylene(s) (BTEX), the aromatic portion of total petroleum hydrocarbons (TPH), or large aromatic ring systems up to at least seven fused rings, such as might be found in creosote. 1.1 This test method covers a rapid method for the screening of environmental samples for aromatic hydrocarbons (AHs) and polycyclic aromatic hydrocarbons (PAHs). The screening takes place in the field and provides immediate feedback on limits of contamination by substances containing AHs and PAHs. Quantification is obtained by the use of appropriately characterized, site-specific calibration curves. Remote sensing by use of optical fibers is useful for accessing difficult to reach areas or potentially dangerous materials or situations. When contamination of field personnel by dangerous materials is a possibility, use of remote sensors may minimize or eliminate the likelihood of such contamination taking place. 1.2 This test method is applicable to AHs and PAHs present in samples extracted from soils or in water. This test method is applicable for field screening or, with an appropriate calibration, quantification of total AHs and PAHs. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM E3029-2015 用于测定荧光光谱仪发射信号相对光谱校正因子的标准实施规程
简介:3.1x00a0;Calibration of the responsivity of the detection system for emission (EM) as a function of EM wavelength (x03bb;EM), also referred to as spectral correction of emission, is necessary for successful quantification when intensity ratios at different EM wavelengths are being compared or when the true shape or peak maximum position of an EM spectrum needs to be known. Such calibration methods are given here and summarized in Table 1. This type of calibration is necessary because the spectral responsivity of a detection system can change significantly over its useful wavelength range (see Fig. 1). It is highly recommended that the wavelength accuracy (see Test Method E388) and the linear range of the detection system (see Guide E2719 and Test Method E578) be determined before spectral calibration is performed and that appropriate steps are taken to insure that all measured intensities during this calibration are within the linear range. For example, when using wide slit widths in the monochromators, attenuators may be needed to attenuate the excitation beam or emission, thereby, decreasing the fluorescence intensity at the detector. Also note that when using an EM polarizer, the spectral correction for emission is dependent on the polarizer setting. (2) It is important to use the same instrument settings for all of the calibration procedures mentioned here, as well as for subsequent sample measurements. 3.2x00a0;When using CCD or diode array detectors with a spectrometer for x03bb;EM selection, the spectral correction factors are dependent on the grating position of the spectrometer. Therefore, the spectral correction profile versus x03bb;EM must be determined separately for each grating position used. (3) 3.3x00a0;Instrument manufacturers often provide an automated procedure and calculation for a spectral correction function for emission, or they may supply a correction that was determined at the factory. This correction can often be applied during spectral collection or as a post-collection correction. The user should be advised to verify that the automated vendor procedure and calculation or supplied correction are performed and determined according to the guidelines given within this standard. 1.1x00a0;This practice (1)2 describes three methods for determining the relative spectral correction factors for grating-based fluorescence spectrometers in the ultraviolet-visible spectral range. These methods are intended for instruments with a 0x00b0;/90x00b0; transmitting sample geometry. Each method uses different types of transfer standards, including 1) a calibrated light source (CS), 2) a calibrated detector......

ASTM D5381-1993(2014) 颜料和填充剂中X射线荧光(XR)光谱仪的标准指南
简介:5.1x00a0;The identification of pigments in a sample of liquid paint or paint film is often important for regulatory purposes. Many inorganic pigments or extenders utilized in past paint formulation are now regulated by federal, state, or municipal health authorities. XRF is one of the more common and convenient methods employed to characterize the pigment composition of a paint formulation. 5.2x00a0;XRF techniques, in general, do not provide the ability to identify the chemical nature of organic pigments. There are instances where XRF techniques, used in tandem with other analytical methods, such as solid state Carbon 13 Nuclear Magnetic Resonance (C-13 NMR), can identify the organic pigments utilized in coatings. However, XRF provides only an elemental sketch of the inorganic pigmentation. The chemical composition of the pigments is inferred by the analyst from the samples, color, elemental information, and common sense. Small impurities are often found in pigments, so the relative XRF intensities also serve to guide the analyst in proposing the probable pigment present. 1.1x00a0;This guide covers the general considerations for proper use of X-ray fluorescence (XRF) spectroscopy. Because many differences exist between XRF instruments, no detailed operating instructions are provided. The analyst should follow the instructions provided by the manufacturer for his instrument. 1.2x00a0;The analyst is encouraged to consult the chemical literature, various trade journals, pigment supplier publications, etc., as well as the instrument manuals from the manufacturer. 1.3x00a0;XRF is commonly employed to determine the elements present in inorganic pigments and extenders, often in concert with other analysis techniques. Organic pigments cannot normally be identified solely by XRF. On occasion, organic pigments contain heavier elements that can distinguish between major classes of these pigments or may serve to distinguish one of the two distinct pigments. However, the analyst should be wary of a qualitative pigment identification solely by XRF technique. 1.4x00a0;This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard information see Section 3 on Radiation Concerns.
