Forensics

Forensic science involves the application of scientific principles and techniques to investigate and solve criminal cases. In forensic laboratories, water quality is a critical factor in various analyses, ensuring the integrity of evidence and the accuracy of results. Impure water can introduce contaminants that might compromise the reliability of forensic analyses.

What Is The Impact Of Water In Forensics?

Water quality plays a crucial role in forensic analyses, impacting the accuracy and reliability of results. Contaminated water may introduce impurities that interfere with analytical techniques, potentially leading to inaccurate findings. Forensic applications often involve sensitive procedures, and the use of high-quality water is essential to maintain the integrity of evidence.
What Types Of Contaminants In Water Can Affect Forensic Analyses?
Forensic analyses may be sensitive to a variety of contaminants, including:

Bacteria & Microorganisms

Impact:
Bacterial contamination can compromise forensic sample integrity.
Effect:
Unintended microorganisms may alter the composition of forensic samples, leading to inconsistencies in experimental conditions and compromising the reliability of forensic analyses. This can affect the accuracy of DNA or other forensic analyses.

Endotoxins

Impact:
Endotoxins can affect the quality of forensic samples.
Effect:
In forensic experiments, endotoxins may lead to changes in sample characteristics, affecting the accuracy of analyses. This can compromise the reliability of forensic results.

Organic Compounds

Impact:
Small organic compounds in water can introduce unwanted signals in forensic assays.
Effect:
Organic impurities, such as humic acids and pesticides, may affect the purity of forensic samples. Removal of these organic compounds from forensic buffers is crucial to ensure accurate and reliable forensic results.

Ionic Contaminants

Impact:
Ionic contaminants can interfere with forensic analyses.
Effect:
Elevated levels of ions may affect the stability and characteristics of forensic samples, leading to variations in forensic results. Maintaining low levels of ionic contaminants is essential for the reproducibility and accuracy of forensic analyses.

Water Measurement Requirements for Forensics

In forensic applications, the accuracy and reliability of analyses are paramount, and water quality plays a crucial role. The choice of water is tailored to the sensitivity of forensic methods employed. For techniques demanding precise results, such as DNA analysis and forensic chemistry, the use of apyrogenic, Type I ultrapure water is strongly recommended.
Water Quality Standards According to Industry Guidelines:

Resistivity (MΩ.cm)*

>18

TOC (ppb)

<10

Filter (μm)

<0.2

Bacteria (CFU/ml)

<1

Endotoxins (EU/ml)

<0.002

Nucleases

Not detected

Adhering to these water quality standards is crucial for the success and accuracy of forensic analyses. Type I water is recommended for critical forensic applications, while Type II water may be suitable for routine analyses.
NOTES:
Applications requiring Endotoxin filtration should purchase a CLF-5000-02E Endotoxin removal final filter.
