Drug used are encased in the hair shaft, which means the longer the hair the longer back traces the lab can detect in the individual’s drug history. the test conducted to illicit result is ______.

A test performed by observation and description of the physical properties of a specimen through a microscope.

Which among the test is an example of a confirmatory test?

This instrument passes a narrow beam of infrared energy through a thin film of the substance being studied, as the wavelengths changes, the amount of energy transmitted by the specimen is measured and recorded on a chart.

An analytical technique used to separate the components of a mixture and subsequently identify them, following MS analysis, a unique spectrum will be produced for each particular compound, which can be compared to spectra of known compounds to determine the identity of components in the mixture.

A qualitative method used to indicate the presence of THC, cannabinol and cannabidiol in a suspected cannabis product.

Used in the field for quick screening of suspect substances

Soil evidence have what kind of characteristics as evidence?

The liquid used in soil analysis.

A method of separating compounds in order to aid in the identification and quantification of a substance, which then analyze into organic materials such as narcotics, plastics, explosives, paints, inks or petroleum products.

The process which refers to knocking one or more electrons from the analyte, producing a positively-charged ion (known as a cation) which is often achieved by a heating the filament which emits electrons to acceleration and focused to knock electrons off the sample molecules, thus producing ions.

Involves the use of a thin layer of stationary phase (typically silica, alumina, cellulose or a gel permeation material) on a flat carrier sheet, onto which the sample is spotted.

Utilizes a solid stationary phase housed inside an analytical column, through which a liquid mobile phase carries the analyte of interest.

Used in forensic Science is considered the most confirmative chromatographic technique which can allow for substances to be identified.

Utilized in the analysis of materials used to make explosives.

The following are the various chromatography methods, EXCEPT;

A physical method of separation in which the components to be separated are distributed between two phases, one of which is stationary while the other moves in a definite direction.

A procedure used to separate mixtures and to identify the components present in those mixtures.

In collecting moisture soil samples, What should be done?

Kinds of evidence that usually associated with outdoors crimes or where the suspect may have walk or drive on unpaved areas, this evidence maybe retain in the cracks or heels of the shoes of the suspect or the suspect may deposit these particles that were picked up outside of the crime scene.

Branch of geology which deals with the systematic classification and identification of rocks, rock forming minerals and soils.

An analytical instrument that can be used to chemically identify an unknown substance essentially based on its molecular mass and charge.

Known as the Kastle-Meyer test, which causes an alkaline solution to take on a pink coloring in the presence of blood.

A test in which a positive result is not conclusive that the stain is blood but a negative result is conclusive that the stain is not blood.

These cell components are formed from pieces of cells found in the bone marrow called megakaryocytes it help blood to clot.

These cells play an important role in the immune system and lymphatic system by defending the body against infection.

The blood cells responsible in carrying oxygen to the tissues.

These cells determine the blood type and are the most abundant cell type in the blood, they have what is known as a biconcave shape.

In the legal sense, blood could be used to, EXCEPT;

The shape of the blood or blood stains will give the investigator an idea of the direction of its source. Usually in small drops, the tapering end of the blood spot is towards the direction of the moving source. In this case, the blood was used to _______.

In the case where a person was found dead with a stab wound on his chest and a knife with blood was found near his body. Examination of the weapon showed that the blood-stained on it belongs to the same blood group as that of the victim. This result shows a strong presumption that the weapon was used to stab the victim. In this case the blood was used as a _______.

A man of average size contains about how many quarts of blood.

The circulating fluid provides the body with nutrition, oxygen, and waste removal.

The Father of Criminal Detection.

He established the first crime lab based upon the idea that criminals leave behind traces of themselves with every crime and stated the principle that once contact is made between two surfaces a transfer of material(s) will occur.

The man who detailed the assistance that investigators could expect from the fields of Microscopy, Chemistry, Physics, mineralogy, zoology, botany, anthropometry, and fingerprinting.
