What is substrate control forensics?
A substrate control is uncontaminated surface material close to an area where physical evidence has been deposited. This sample is used to ensure that the surface on which a sample had been deposited does not interfere with laboratory tests.
What is a substrate in forensic science?
substrate control. Uncamamined surface material close to an area where physical evidence has been deposited.
What is mobile forensic science laboratory?
“Mobile Forensic Van” (MFV) is being launched by Gujarat Forensic Sciences University (GFSU) and Helik Advisory Ltd which helps in reaching the crime scene at the earliest to assist the Investigating Officers (IOs) in identifying and collecting relevant forensic evidence from crime scene, victims & from suspects which …
What is a control sample in forensic science?
An important aspect of collecting evidence is properly obtaining control samples, which are samples taken from a known source against which the examiner can compare samples taken from the crime scene.
Which type of evidence should be collected first?

What is the difference between a CSI and a forensic scientist?
While crime scene investigators work at crime scenes and collect evidence, forensic science technicians work in laboratories and examine the evidence that has been collected for possible clues about what happened and who might be responsible for the crime.
What is an example of substrate control?
Another common example of a substrate control is a material on which a bloodstain has been deposited. Unstained areas close to the stain may be sampled to determine whether this material can interfere with the interpretation of laboratory results.
What are the important part of mobile devices used in digital forensics?

Why is mobile forensics important?
The mobile forensics process aims to recover digital evidence or relevant data from a mobile device during a way which will preserve the evidence during a forensically sound condition. to realize that, the mobile forensic process must began precise rules which will seize, isolate, transport, store for analysis and …
How do you control a sample?
Control samples, sometimes referred to as substrate samples, are swabbings or cuttings from an unstained portion of the surface material near the recovered stain. The control sample should be packaged separately and clearly labeled.
