It sets out, the cross contamination of pervious drug, foreign matter are mixed into order to prevent, carry out the cleaning validation of the evaluation test of drug residue
It is critically important.The device for carrying out assessment confirmation as the drug residue to manufacturing equipment also has HPLC (high performance liquid chromatograph),
But due to needing solvent extraction, the depending on the circumstances or the needs of the situation pretreatment such as concentration, so measurement needs the time.
On the other hand, since combustion-type solid sample measuring device does not need to pre-process, can hold in a short time
It changes places and detects the residual quantity of drug.
The sampling method of cleaning validation has elution method and wipe method, but U.S. FDA, Ministry of Health, Labour and Welfare height are assessed and recommended
Be wipe method.In wipe method, due to coming the one of wiping device surface by using the Wiping material of quartz glass fibre
Area (usually 10cm × 10cm) is determined to physically acquire and analyze attachment residue, even so with elution method hardly possible
With the insoluble attachment of acquisition, also it is able to carry out wiping and acquires.
In the measurement of combustion-type solid sample, originally needs the extraction water from Wiping material and measure, it at this time can be with
Wiping material after wiping is placed on example boat to and is measured each Wiping material, thus can it is very fast and accurately into
Row measurement operation (for example, referring to patent document 1).
In sampling, carries the example boat that placed Wiping material and be moved to the manufacturing equipment as object, pass through wiping
Material is wiped to wipe certain area on manufacturing equipment surface, Wiping material is placed on example boat on the spot and takes back combustion-type and is consolidated
Some analysis room of body sample measuring device measures total carbon.

Summary of the invention
Utility model will solve the problems, such as
The Wiping material for having wiped certain area on manufacturing equipment surface is placed on example boat and from manufacturing equipment
Some facility is moved to the analysis room for carrying out residue assessment.Therefore, it when analyzing indoor measurement, needs to shift example boat
To the defined position of specimen holder.In addition, in the movement from the facility of manufacturing equipment to analysis room, sample (Wiping material)
It can probably be polluted by dust of outside air etc..
The operation that example boat is transferred to specimen holder is not only taken time and energy, but also can probably be generated because being polluted in the operation
The sample (Wiping material) that is carried on example boat and lead to not the risk correctly measured.
The purpose of this utility model is to provide a kind of combustion-type solid sample measuring device specimen holders, do not need
Example boat is transferred to specimen holder in analysis room, and sample will not be kept dirty because of dust of outside air etc. on the move
Dye.
Technical means to solve problem
To solve the above-mentioned problems, it on the combustion-type solid sample measuring device specimen holder described in technical solution 1, wipes
The Wiping material for having wiped certain area on manufacturing equipment surface is arranged on example boat, and utilizes example boat operating stick, is wiped
It wipes material to be fed in heating furnace together with example boat, is provided with example boat in advance in the specimen holder, is thus configured to
When sampling, specimen holder is moved into the manufacturing equipment as object, and certain area on manufacturing equipment surface will have been wiped
Wiping material is accommodated in example boat.
In addition, being arranged on the specimen holder in combustion-type solid sample measuring device specimen holder described in technical solution 2
There are the lid of example boat of the covering configuration on specimen holder, the combustion-type solid sample measuring device sample described in technical solution 3
In product frame, there is handle on the lid being arranged on specimen holder.Further, it is arranged on specimen holder by inert gas purge
Lid in it is more effective.
The effect of utility model
Combustion-type solid sample measuring device specimen holder according to the present utility model is provided with sample in advance due to carrying
The specimen holder of boat and it is moved to manufacturing equipment as object, so wiping manufacturing equipment by Wiping material in sampling
Certain area on surface, and be on the spot contained in Wiping material (sample) in the example boat configured on specimen holder, thus, it is possible to
Save the effort that example boat is transferred to specimen holder in analysis room.Further, since will not in the operation for being transferred to specimen holder
There is unnecessary touching to example boat, therefore reduces sample (Wiping material) contaminated risk.
Further, the lid of example boat being configured on specimen holder due to being provided with covering, thus can prevent from into
Gone sample sampling manufacturing equipment into the movement for the analysis room for being provided with combustion-type solid sample measuring device produced by
The pollution from outside air.Further, since sample is covered with handle, so the carrying of specimen holder (example boat) is held very much
Easily.
As described above, can surveyed by using the combustion-type solid sample measuring device specimen holder of the utility model
It measures in the combustion-type solid sample measuring device of each Wiping material, can be very fast and accurately measures operation.
Detailed description of the invention
Fig. 1 is the combustion-type solid for indicating to have used the combustion-type solid sample measuring device specimen holder of the utility model
The figure of sample measuring device constituted substantially.
Fig. 2 is the figure for indicating an embodiment of combustion-type solid sample measuring device specimen holder of the utility model.
