Description:

When referring to heavy metals from an environmental pollution perspective, it mainly refers to metals or metal-like substances such as mercury, cadmium, lead, chromium, arsenic, and also includes generally toxic heavy metals such as copper, zinc, nickel, cobalt, tin.

Quantitative Testing Techniques for Heavy Metals:

Commonly recognized methods for heavy metal analysis include ultraviolet-visible spectrometry (UV), atomic absorption spectroscopy (AAS), atomic fluorescence spectroscopy (AFS), inductively coupled plasma (ICP), X-ray fluorescence spectroscopy (XRF), inductively coupled plasma mass spectrometry (ICP-MS). In addition to the above methods, spectroscopy is also introduced for more accurate and precise testing.

Common Heavy Metal Testing Project Analysis:

1.Comparative Analysis of Heavy Metals: Usually involves qualitative and quantitative comparison of heavy metal compositions in two products, focusing on the differences in composition and quantities of heavy metals.

2.Identification of Heavy Metal Materials: Primarily used for heavy metal analysis services provided by relevant materials.

3.Analysis of Heavy Metal Failures in Products: Utilizes various constants, tracking, and tracing analysis techniques to analyze and diagnose the causes of heavy metal quality incidents in products.

4.Analysis of Heavy Metal Elements: Identifying the presence and content determination of heavy metal elements in organic substances, which is a general term for determining heavy metal element concentrations.

5.Unknown Heavy Metal Analysis: Refers to the technical methods of spectrally analyzing unknown heavy metal components. This technique is similar to “reverse engineering” in the legal profession, aiming to determine the heavy metal composition by dismantling, testing, and recombining the target product.

6.Qualitative and Quantitative Analysis of Heavy Metals: Refers to the quantitative relationships or quantitative relationships of heavy metal components in the analyzed research objects. It also involves quantitative analysis and comparison of several attributes, characteristics, and interrelationships of the objects.
