BDS - Base deactivated Silanol
ODS - Octadecyl silane
by using the BDS column, residual silanols deacivated and silanol
activity reduced, it is end-capped column and it is good for
basic compounds.
ODS is normal column and high acidic silica, it is not suitable for basic
compounds.

How do you distinguised np-hplc and rp-hplc?
NP-HPLC is "Normal Phase" HPLC, wherein the solvents used are less polar than the substrate in the HPLC column (e.g. using hexane or dichloromethane with a silica HPLC column). RP-HPLC is "Reverse-Phase" HPLC, wherein the solvents used are more polar than the substrate in the HPLC column (e.g. using Water and Methanol with a octadecylsilane (ODS or C18) column).
What is difference between inertsil ods 3V and inertsil ods 4 column?
Both are same
Why is the ozone deteriorating?
The ozone layer is diminishing because of the excessive use of ozone depleting substances by the humans. These ODS contain chemicals which react with the ozone in the ozone layer and deplete it.

What is Difference between ODS column and BDS column in column chemistry?
ODS means octadecylsilane and BDS means base deactivated silica.

What is ODS-Petrodata's population?
The population of ODS-Petrodata is 100.
When was ODS-Petrodata created?
ODS-Petrodata was created in 2002.
Full form of ODS?
The Full form of the acronym ODS is operational data store
What you can do to protect ozone layer?
To protect ozone, stop using ODS. CFC's is one of the main ODS.
How control ozone deplection?
The ozone depletion can be controlled by minimizing the use of ODS. These ODS contain CFC which deplete ozone.
Full form of ods Ozone diplition substance?
ODS stands for Ozone Depleting Substances. These include freons, CFC's etc.
How are we going to minimize the uses of ozone depleting substances?
Minimizing the use of ODS has led to the need of other products. We can minimize ODS by using their alternates.
What are the three natural phenomenons that affect the ozone layer?
Various phenomenon affect ozone. The three are : UV rays, Man made ODS and natural ODS.
What do aerosol produce?
Aerosols produce CFC's. They are ODS.
